is it possible to save the entityskin with the actual shader effect in a bmap?
i mean i have a entyti with a crome effect and i want to create a new bmap and write and save the skin with this effect in the new bmap?

yes, thats possible with the use of bmap_process.

I don't have experience with it so I can't help you further, but it looks like you will have to use bmap_to_format and then you can save it with bmap_save into a bmp file which you can then manually set as entity skin.

thanks, i know bmap_process, its for use panel shaders
and uses pp-shaders
but how i have acces to the rendertarget bmap of the entity?
