Don't feel sorry yes this is the issue and since Knot ID are not ordered from right to left but from creation order its why it's confused you. Moreover, using a for loop will make way more sense and help you to avoid this kind of stuff. grad1 = shdr1[c4d.SLA_GRADIENT_GRADIENT] grad2 = shdr2[c4d.SLA_GRADIENT_GRADIENT] for knotId in xrange(grad1.GetKnotCount()): knot = grad1.GetKnot(knotId) grad2.InsertKnot(col=knot['col'], pos=knot['pos'],index=knot['index']) grad2.FlushKnots() shdr2[c4d.SLA_GRADIENT_GRADIENT] = grad2 Finally, a BaseShader is derived from BaseList2D which is derived from C4DAtom that mean you can use GetClone to retrieves a clone of this shader so your code can look like. import c4d def main(): mat = doc.GetFirstMaterial() colorShader = mat[c4d.MATERIAL_COLOR_SHADER] if colorShader is None: return copyColor = colorShader.GetClone() mat[c4d.MATERIAL_DIFFUSION_SHADER] = copyColor mat.InsertShader(copyColor) mat.Message(c4d.MSG_UPDATE) mat.Update(True, True) c4d.EventAdd() # Execute main() if __name__=='__main__': main() Cheers, Maxime.

Thanks Sebastian! Looking forward for a fix. ;) Meanwhile I'll take care of your recommendation. Best, Robert

Hi Daniel, I filed a bug report with regard to this unexpected behavior. I will keep you updated on resolution. Best, Riccardo

Hi, thanks for pointing this out to us. Yet, we were not able to reproduce this issue. What we found so far, when doing a search for "EventAdd()" (or anything similar resulting in a large number of results) and the search is set to show posts instead of threads, then switching between result pages can indeed take some time (at least for the first switch). During this time the page is indeed completely unresponsive and seems frozen, which is not nice. But here it always returned and showed the expected content after a bunch of seconds (I think in my tests longest was about 15 seconds). We'll keep an eye on this. Cheers, Andreas

Hi @Fransua welcome in the plugincafe community. Do not worry since it's your first post but please read and follow these rules (I've setup your post correctly) How to Post Questions especially the tagging part. Q&A New Functionality. Unfortunately, a complete list is not available for the moment. But if you are looking only for object there is this page Object Types and Fields Object Types which refer to all symbols available to describe an object. To know a specific object id, you can drag and drop this object/element to the console, for more information see Python Console, Scene Elements. Finally, you can also retrieve for the full list of id by their type with c4d.plugins.FilterPluginList Cheers, Maxime.

@a_block Hi Andreas, Thanks for your help and you are never too late! That actually makes more sense. Unfortunately I can't seem to replicate the issue again on my machine, as it seems that it's been working for all my updates. I will have a look on one of my team machines when released and see if that could be the problem. Thank you again!

Thanks, Andreas! I was looking for interface_icons_2x for a while

Hi @lasselauch as @mp5gosu this is a urrlib2 issue and we can't provide support on this topic. Moreover, if you have more questions (while I think everything is said), please open a new thread since while the overall topic is related, the question and issue are different. Cheers, Maxime.

Just tried now… It seems to work perfectly! Thank you! I don't want to boring you, but, please, don't disable this super feature in python. Instead you could update the documentation specifying well how to use it.

Hi Pyr, thanks for reaching us. With regard to the issue you reported, it looks like there's something unexpected happening that instead of returning the computed cache, regenerate and returns a new cache. Although it might occur that switching between documents require the generator to recreate the cache, switching between view definitively it's not supposed to happen. Considering that your information doesn't actually help too much in understanding how you're evaluating cache dirtiness nor what changes are you're checking in the vertexmap, could please post fragments of the code or, alternatively, try to reuse your cache dirtiness mechanism on an "simpler" plugin to see if it works reliably? Looking forward further comments, give best. Riccardo

Hi Rage, thanks for reaching us. With regard to the issue mentioned and considering your non-Cinema background, first of all lets settle down a few concepts: UVWTags are just acting as "storage" for the UVW data used on polygonal objects; TextureTags are instead used to create the actual texturing on the on a generic object (whatever it's a polygonal or parametric one) A parametric object can use a texture even without explicit an UVWTag since the TextureTag delivers all the information with regard on how to map a texture to the object. When a parametric object (e.g. cube) is converted into a polygonal one the UVW values which are part of the parametric object gets dumped in the UVWTag that is generated as soon as the conversion ends. That said give a certain object (a polygonal one) the way to go is: def main(): # check that an object is selected if op is None: return # get the active material activeMat = doc.GetActiveMaterial() if activeMat is None: return # instantiate a TextureTag sph50NoTileTextureTag = c4d.TextureTag() if sph50NoTileTextureTag is None: return # set the mapping type sph50NoTileTextureTag[c4d.TEXTURETAG_PROJECTION] = c4d.TEXTURETAG_PROJECTION_SPHERICAL # turn off tiling sph50NoTileTextureTag[c4d.TEXTURETAG_TILE] = False # scale the mapping to 50% on u and v sph50NoTileTextureTag[c4d.TEXTURETAG_LENGTHX] = 0.5 sph50NoTileTextureTag[c4d.TEXTURETAG_LENGTHY] = 0.5 # link to the active material sph50NoTileTextureTag[c4d.TEXTURETAG_MATERIAL] = activeMat # generate the corresponding UVWTag using the mapping settings specific in the TextureTag sph50NoTileUVWTag = c4d.utils.GenerateUVW(op, op.GetMg(), sph50NoTileTextureTag, op.GetMg()) # check for UVWtag being properly created if sph50NoTileUVWTag is None: return # set the name of the tag sph50NoTileUVWTag.SetName('0.5 non-tiled spherical') # add both the UVWTag and the TextureTag if op.GetTag(c4d.Tuvw) is None: op.InsertTag(sph50NoTileUVWTag) if op.GetTag(c4d.Ttexture) is None: op.InsertTag(sph50NoTileTextureTag) # notify Cinema about the changes c4d.EventAdd() Best, Riccardo

Hi, thanks for pointing out this issue. We'll see if can get a fix for that (not all tags visible, if zooming in with browser). In the end Maxime wasn't referring to tags at all. Instead he was talking about the Q&A Function we have in this forum. I took the freedom to mark this thread as solved (see this shiny green stamp next to the headline ). Cheers, Andreas

Hi, GeAllocTypeNC() was already removed from the API with version R15 (see API Change List in R15 and maybe more interesting for you Transition to Cinema 4D R15 API). You are already on the right track using NewMem(), now in R20, there's an additional change, which bites you here: The error handling. This indeed is quite an important topic and (of course no bragging involved at all) a really nice feature in the new MAXON API. But it's also the one thing that causes most needed changes for R20. The point is, here at MAXON we do not take error checking lightly. Actually quite the opposite, we enforce error handling where ever we can and our internal developers have no chance to get away without. So, before I provide the solution, here the recommendation to take the time to read the manuals about the Error System. Additionally I recommend the manuals about classic API Entity Creation and Destruction and its MAXON API sibling about Memory Allocation. The additional means you get provided with in the new MAXON API can really make your life easier. I apologize for writing so much before coming to your actual issue. In the end NewMemClear() now returns an Error Result, which basically encapsulates the actual return value and needs to be evaluated in order to get the actual return value. No worries, this is done in a highly optimized form, so it should not impede your code's performance in any way. If you take a look at our SDK examples, you will find quite a few places, where error handling in conjunction with NewMem is demonstrated in various ways. Cheers, Andreas

Seems like this is a way to go. LONG TEST_BUTTONS {CUSTOMGUI QUICKTABRADIO; CYCLE{ TEST_1; TEST_2; TEST_3; }FIT_H;} Previously my mistake was that I was writing CUSTOMGUI QUICKTABRADIOBUTTON instead of CUSTOMGUI QUICKTABRADIO

Thanks, Maxime! I will use that in the meantime. Edit: Why can't I flag your posts as the correct answer? I can only flag my own.

@m_adam said in Spline modeling commands via OBJECT_MODIFIER (Python): Maxime Thank you, Maxime for your explicit and informative answer! I'll take a look into it.
