Hello blender gurus,
I just realized that you can only have 15 materials for a single Object in
blender. Would anyone know why this limitation is necessary? What do people normally do to get around with this problem (other than using less
than 16 materials)?
Thanks a lot.

Hi, didu, I unfortunately can’t answer you question, but you have made me realise something.
I’ve been trying to render a very detailed scene using Blender’s radiosity solutions, I couldn’t work out why I couldn’t join all the objects in the scene together, (needed to do this cos radiosity started to pinch meshes during the render.), but it is due to the 15 material limit I’m sure.
When radiositised the materials were limited to 15 (all vertex colours no textures) as you mentioned, maybe there’s a workround that can be implemented into the source, look into this I must.
Sorry I couldn’t help you but thanks for pointing out the problem I couldn’t identify,
Sonix.
you will have to use multiple objects, each one can only have 16 materials
why?
the datatype used for objects is limited in that manner. (it is in the code)
It could be changed but the files will not work with older versions of blender.
Hi,
I’m glad to be helpful 
!
I’ve throught about using multiple objects, but the problem is that, if you
only have one mesh with lots of polygons of different material, then
multiple objects probably won’t work.
Anyway, would anyone know the cvs tag of blender version 2.26/2.25?
I might just have a go at this problem.
Also, I’ve just compiled version 2.27 checked out from the cvs repository.
Everything looks fine EXCEPT resizing the sub-windows horizontally and
vertically, when I tried to resize a sub window by dragging its border, the
border just keeps flashing and wouldn’t settle down no matter which mouse
button(s) I press. Would anyone know what I did wrong?
Thanks a lot.
