Title: shader question
Post by: morsix on December 02, 2013, 04:34:39 am

I'm new to Unity and 2D Toolkit, and I have a question regarding doing a texture mapped cutout of a sprite.. is it possible to make a black/white "map" of which parts the of the 2d toolkit sprite should draw and be able to apply that as a material?

Anything I try it failing to "stick" when I try and set a material in the collection.. always reverts back to the atlas..

I've never tried anything before so I don't know if I'm going in the right direction or not..

WRT material in the atlas - that is expected, and required for multiple atlas spanning and multiple material support per atlas. If its for a specific sprite in an atlas, you can try the multiple material feature (http://www.2dtoolkit.com/docs/latest/tutorial/multiple_materials_in_a_sprite_collection.html).

It is possible to do that clipping thing, check this sample here - it doesn't do exactly that (its a rectangular cutout instead), but you could use it as a basis for your experiments.
