@ferdinand,
There is something weird going on. I intend to change several sliders accordingly to Parameters, ID_X and ID_Y. I adapted the code accordingly, but it seems that only DESC_MAXSLIDER and DESC_MINSLIDER are took into account while DESC_MIN and DESC_MAX stick to previous values. Could that be a bug?
Parameters
ID_X
ID_Y
DESC_MAXSLIDER
DESC_MINSLIDER
DESC_MIN
DESC_MAX
I let in remarks the code that improve a bit better the result and allows ID_X to be fully set (MIN/MAX as well as MINSLIDER/MAXSLIDER), but the problems remains on ID_Y.
Here the whole code of GetDDescription(),
GetDDescription()
global Parameters Parameters = dict() Parameters['Xmin'] = -360.0 Parameters['Xmax'] = 360.0 Parameters['Ymin'] = -25.0 Parameters['Ymax'] = 25.0 def GetDDescription(self, node, description, flags): if not description.LoadDescription(node.GetType()): return False # Change Slider limits accordingly to Parameters values # Sliders to modifiy ID_X, ID_Y ## SLIDER ID_X if len(Parameters) > 0: paramID_X: c4d.DescID = c4d.DescID(c4d.DescLevel(ID_X, c4d.DTYPE_REAL, 0)) single_X: c4d.DescID = description.GetSingleDescID() # Bail when there is a to be evaluated parameter and our parameter is not part off or equal to the to be evaluated parameter. if single_X and not paramID_X.IsPartOf(single_X): return True, flags # if singleId[0] == mAXIS_X: print (f"singleID found: {singleId} ") # Get the description data container instance (GetParameter>I<) for the parameter we want to modify desc_X: c4d.BaseContainer = description.GetParameterI(paramID_X) if desc_X is None: return True, flags # if single_X and paramID_X.IsPartOf(single_X): # if paramID_A1.IsPartOf(single_X)[0]: # Write the MAX and MAXSLIDER values based on UserDatas desc_X[c4d.DESC_MIN] = c4d.utils.DegToRad(Parameters["Xmin"]) desc_X[c4d.DESC_MINSLIDER] = c4d.utils.DegToRad(Parameters["Xmin"]) desc_X[c4d.DESC_MAX] = c4d.utils.DegToRad(Parameters["Xmax"]) desc_X[c4d.DESC_MAXSLIDER] = c4d.utils.DegToRad(Parameters["Xmax"]) # if single_X and paramID_X.IsPartOf(single_X): # if paramID_X.IsPartOf(single_X)[0]: # print (f"Found X: {paramID_X.IsPartOf(single_X)[0]} ") # return (True, flags | c4d.DESCFLAGS_DESC_LOADED) ## SLIDER ID_Y paramID_Y: c4d.DescID = c4d.DescID(c4d.DescLevel(mAXIS_Y, c4d.DTYPE_REAL, 0)) single_Y: c4d.DescID = description.GetSingleDescID() # Bail when there is a to be evaluated parameter and our parameter is not part off or equal to the to be evaluated parameter. if single_Y and not paramID_Y.IsPartOf(single_Y): return True, flags # Get the description data container instance (GetParameter>I<) for the parameter we want to modify desc_Y: c4d.BaseContainer = description.GetParameterI(paramID_Y) if desc_Y is None: return True, flags # Write the MAX and MAXSLIDER values based on UserDatas desc_Y[c4d.DESC_MIN] = c4d.utils.DegToRad(Parameters["Ymin"]) desc_Y[c4d.DESC_MINSLIDER] = c4d.utils.DegToRad(Parameters["Ymin"]) desc_Y[c4d.DESC_MAX] = c4d.utils.DegToRad(Parameters["Ymax"]) desc_Y[c4d.DESC_MAXSLIDER] = c4d.utils.DegToRad(Parameters["Ymax"]) # if single_Y and paramID_A2.IsPartOf(single_Y): # if paramID_Y.IsPartOf(single_Y)[0]: # print (f"Found Y: {paramID_Y.IsPartOf(single_Y)[0]} ") # return (True, flags | c4d.DESCFLAGS_DESC_LOADED) return (True, flags | c4d.DESCFLAGS_DESC_LOADED)
Does this trick to change REALSLIDER MIN/MAX values intend to be associated to only on change, and not on several UI object?
Thanks in advance, Cheers,
Christophe
You can add the following code to see the values before and after new assignment. You will see that the values are correctly changed, but the change does not reach the interface for unknown reason.
for k,v in desc_Y: print(f"Y New, Key {k} / Val {v}")
Hey @mocoloco,
So, I gave it a spin and the root of your problems is that you defined your parameters as UNIT DEGREE where you and I used METER in the first examples. When you do so, you must define your values in radians, not degree when you write into the raw data.
UNIT DEGREE
METER
But there are also some weird things going on with DEGREE. First of all, min-max slider values are always set to null\None in the description container, no matter how often you write the values, and the general min/max values seem to be used instead. One could sort of make sense of that, but what is really weird how the first parameter in a group does behave.
DEGREE
null\None
Fig. I - Unit Degree: We set the min-max range and name for both parameters. Setting the name works on both, but the first parameter adopts a clamped range which is a weird mix of its old and new value. The second parameter works fine.
Running the same code but using METER as a unit works without any issues.
Fig. II - Unit Meter: Here both parameters work flawlessly.
There is either a bug in the degree description handling, or you must jump through some hoops and set up the data in a specific way. I will not have the time to test this in more detail before next week. To help yourself, I would suggest defining either via user-data or a resource file a REAL DEGREE parameter and then reading out all its description values, looking for anything special that might be going on.
REAL DEGREE

Hi @ferdinand,
Thanks a lot for your time on this and sorry for the wrong unit on the first example I submitted with METERS instead of DEGREES - at the sometime it seems that it raised some kind of bug link to this ^^.
METERS
DEGREES
Like you wrote, I did convert the value in Radian for all the Parameters and so, but anyway the problem seems linked to the simultaneous use of UNIT DEGREES; CUSTOMGUI REALSLIDER in the resource file.
UNIT DEGREES; CUSTOMGUI REALSLIDER
I ran a couple of tests and I noticed the following: • When only using REAL without CUSTOMGUI REALSLIDER; in the resource file, the field behaves as it should and limits changes works as expected • When using CUSTOMGUI REALSLIDER; with UNIT METERS; it does work as well as expected • When using UNIT PERCENT; with MIN -100.0; MAX 100.0 and assigning the values by multiplying the slider value by Parameters[--max], printing and assigning the result to a STATICTEXTit displays the right value in degree or rad depending on the final conversion made prior display. • When assigning UNIT DEGREES; with CUSTOMGUI REALSLIDER, I'm getting weird behaviour like said previously and like you noticed.
REAL
CUSTOMGUI REALSLIDER;
UNIT METERS;
UNIT PERCENT;
MIN -100.0; MAX 100.0
Parameters[--max]
STATICTEXT
UNIT DEGREES;
CUSTOMGUI REALSLIDER
I haven't had the time to ran test today with INTERFACE_DATA like you suggested. I will try to do that tomorrow and I will keep you in touch about this.
INTERFACE_DATA
Cheers, Christophe
No need to be sorry. For UNIT PERCENT you will have to write values as decimal values, i.e., 100% is 1.0.
UNIT PERCENT
100%
1.0
The root problem is the weird behavior of MINSLIDERS and MAXSLIDERS not being written when messing with the description when the unit is percent. The best way to check for possible "tricks", would be to inspect a valid existing description for a REAL, UNIT DEGREE parameter to see what is what.
MINSLIDERS
MAXSLIDERS
REAL, UNIT DEGREE
And as stated in my last posting, I unfortunately will not have the time to debug this this week, but I will give it a spin next week.
I was quite sure indeed that UNIT PERCENT will work, but I give a try to see. What I do not understand is, when I'm printing all the values existing in desc_X or desc_Y, they looks good, the value is correct, but not took completely into account on the drawing side for CUSTOMGUI REALSLIDER.
desc_X
desc_Y
Like I said, if I remove the CUSTOMGUI REALSLIDER; option in the resource file and using REAL as a standard input field, whatever the UNIT I'm using, everything behaves correctly. MIN/MAX values are correctly assigned even though there is multiple REAL that need to be change. That let me lead like you to a bug linked to CUSTOMGUI REALSLIDER when only using UNIT DEGREE.
UNIT
MIN/MAX
No problem to have a look on this next week. I can deal with that for the moment using PERCENT, as is produce slightly the same result. It is just not really convenient to guess a percentage for an angle, but that's OK.
PERCENT
Many thanks, Cheers,
I had time to revisit this today with less time pressure than I had before. I made some mistakes in my prior answer:
MINSLIDER
MAXSLIDER
You can see here the effect for the same plugin I used in my prior posting, where both parameters are initialized as [-90°, 90°]. The first one is then changed to [-45°, 45°] and the second one to [-180°, 180°]. The first parameter works fine, while the second one exhibits the effects described above with both the value and slider clamp range being unchanged while the slider position reflects the new value.
[-90°, 90°]
[-45°, 45°]
[-180°, 180°]
Fig. I: When the unit is DEGREE, increasing the value and slider range will fail. Also shown here, I compare the description of our modified bar.y parameter with a user data parameter of the same date type, unit, and range. The values are identical.
bar.y
I also talked with one of our GUI developers and he does not see any problems with the code we use either. This is very likely a bug, since the data in the description is the same (bar.y and data.x in the example screen cast above and the print out below), but treated differently, when and only when the unit is DEGREE. I have filed an issue for that in our bug tracker.
data.x
I currently also do not see any good workaround for this for you. You will have to wait for a fix or the dev untangling the core issue and telling us how you can work around this. I have for now classified the issue as low priority, which means it might take some time before we get to it.

Good morning @ferdinand,
Thanks a lot for taking time going though this. That's exactly what I noticed last week. Changed are took into account but they are not reflected on the GUI. The only workaround that seems possible at this moment is to set MIN/MAX sliders values beyond the possible values that could be set on UserData. Doing so GUI should behave correctly.
Could you please let this thread unsolved for the moment, the time we get a fix on this?
Have a great day, Cheers,
@mocoloco said in Can REAL MIN / MAX value be changed on Init?:
Typically, we track to be fixed issues with the to fix tag which I have also added to your thread here. With that we know where to look once we fixed the issue to announce the fix. What would be the advantage of letting this topic unsolved for you? Youl will also get notified when there is a new reply in a solved topic, e.g., us announcing that we fixed something.
Oh, I didn't know about the to fix tag. Keeping unsolved was much more for the community I the meantime I setup the resource file as discussed, and indeed, having higher values prior setting them solve the GUI problem / which is a good fix for me.
Thanks a lot, Cheers,
