achieving solid color materials wo any shading

[Brian Jones]

one solid color can be done with luminance in the texture, or by using disks instead of spheres… the only way I can think of to do additive mixing though (like your last image) is to use spot lights shining down on a flat white surface (make the inner angle the same as the outer angle for sharp edges).

Thanks a lot, that worked.

Im going to try making the floor have luminance and the material of the balls translucent. Wondering if there will be a way to make the light multiply this way. I know real glass wouldn’t behave this way but will dig to see if theres a way to accomplish this.

Thanks again
