i am currently making a entity material/light editor but i have hit a snag. when i assign a material to the entity and assign a variable to the different things inside the material (diffuse red, ambient green .e.g.) it produces a runtime error. any help?

random guess, assign the vars then the material to the entitiy?

no, still not working...

Can you post your material script?

kk

here is the whole thing. the problem is changing the ambient blue to the variable 'ambl'.

Set the ambient_blue to 0 in the material.
Then use this:"mtl_smaragd.ambient_blue = ambl;" in a function(like the main) and it works!

Ya, thanks!
