How many materials can multimaterial hold and operate without shuting down whole 3ds max?

hajnis

Hi,

3dsMax 2018 sp.3
I have 600-slot multimaterial(5% of slots is occupied) and this simple function which adds new materials into it:

-- tempMatDataItem -- structure which holds material and other info

matLibrary.materialList[tempMatDataItem.newMatID] = tempMatDataItem.mat<br>
The problem is that many times when this method is called 3ds max just shut downs without any warning.

I realized( correct me if I am wrong) that this amount of 600 sub-materials in one multiMaterial is just too much for max to handle->
So I wanna ask, what is the reasonable count of multimaterial slots that 3ds max can handle?

Thanks for response.

I can scarce think of a situation where a single object would need that many materials on it. What is this cyclopian object you are making?

i'd imagine the theoretical limit is 2^32 or 2^64 but why in hell you'd need that is totally beyond me. 

my advice - find another way

via the dialog it's hard coded to 1000, though you maybe able to via the sdk or mxs to a higher value.
