No, the only thing you can really do at the moment is alter an existing shader you aren't using. The built-in shaders (in addition to multi.fx) that use external textures are:

filmreel (1 external texture)
gasmask (2 external textures)
rain (2 external textures)
refract (1 external texture)

Remember, all the other shaders can duplicated/renamed as many times as you need, because they don't use external textures.

thats to bad then. Well got to do what you can.

Thanks for the information and your time in explaining why this could not be done. I will tinker with the other multi shaders and see what I can come up with to accomplish what I want.

Thank you.

We expanded the posteffect slots ourselves to 5 for our developments and that seems about a good amount. We've only used 3 out of the 5. A few may need more down the line, but having the 5 added to the source may be good for others.

Would I add them in these sections in bold?

Are you asking if this is where you would "expand" the slots? If so, no. The slots are defined in the engine source. The post effects that use texture(s) are defined and loaded. The only way to expand is to have the source add slots to allow developers to make/add their own, such as how we did to our source. Bond used multi as a slot- he could use something like "user1", "user2", etc and allow for one or two textures per slot. Then the developer just needs to name the shader/texture file(s) according.

Oh, I see. Then I will have to wait for the extra slots to be available in the sorce code.

Thanks for the explination.

thanks, bond1, for this really nice fx.
