I have a plugin (not mine) that produces an error, while Cinema 4D is loading the plugins.
The error is:

Error reading resource
file '/Applications/Maxon/CINEMA 4D R16 Beta/plugins/ColourTableR13/res/c4d_symbols.h'
Line 40

In line 40 of the c4d_symbols.h file, the line reads:

COLOURTABLE_M_MASK = 0xFFFFF000, // use to determine menu

I converted the hexadecimal value to decimal and changed the line to:

COLOURTABLE_M_MASK = 4294963200, // use to determine menu

But I still get the same error.
What could it be?

Hi Rui,

the IDs are signed 32-Bit integer. So you are actually trying to set a negative value here.
Interpreting 0xFFFFF000 as signed 32-Bit integer actually ends up being -4096. The symbol parser is a bit picky here, as it expects signed values and expects the user to explicitly have the sign for negative values. I mean for the decimal value it is absolutely correct, as the value can't be displayed as a signed 32-Bit integer, but one might discuss, if the hex value should be ok.
Using -4096 (0xFFFFF000 as signed 32-Bit integer) in c4d_symbols.h actually works, though I'm not convinced it's a good idea in the end. I'd rather say stick to values ranging from 0 to 2147483647 (0x7FFFFFFF).

Thank you for the answer, Andreas.
So, should I keep it as hexadecimal? Because this seems to be used as a mask.

Ooopsy, just realizing, you are looking at my very own source... didn't touch it for quite a long time... and indeed I did some strange things back then. Nowadays I probably wouldn't define masks in that place, rather do it in some header file, Cinema is not parsing.

I have a new version that plugin, which will probably never get uploaded (I never received much feedback, so I figured nobody would be interested). If you want, I can send it to you. Even more confusing code, but who knows what it's good for.

Ahahahahahahah!! It is a small world, after all.
Yes, this is ColorTable.
I was asked by someone who bought some of my plugins if I would make it work for R15, R16 and R17 since it was a plugin that he used a lot in R13.
Is it possible to make it work for those versions?

Sure. Actually the current version also works in R17, but it changed quite a lot...
I don't think, it will be much work to get the old version running in R15-R17.

I also wouldn't mind, if you want to take over the code. As long as you keep my name in there somewhere, you could do whatever you want with it.

Sure. Of course I would not take credit for it
