Previewing lightmaps in Max 2009 viewports?

capone

Have a diffuse and lightmap that I want to test together in the viewport without having to keep rendering it with RGB multiply etc.

Tried using the lighting.fx under directX and it screws up the mapping on the diffuse even though it's set to correct channel.

Tried Doyell's shader from game-artisan, doesn't work with my setup. Xoliul's shader doesn't have the feature.

Any help would be much appreciated!

If I remember correctly ShaderFX does texture blending in the viewport. It's free to individual users probably worth getting it even if it doesn't, its all about displaying fx in the viewport. Pretty awesome and super easy to use.

IIRC, I've used a Composite material with the "show in viewport" thing turned on, but this was from a big while back.

This. Lighting is calculated using diffuse*lighting. So just slap in the diffuse and multiply that bitmap with the lightmap.

Thanks for the suggestions guys. Been playing around with lumonix but having trouble creating a lightmap. A*B is a multiply isn't it? need to create a second texturemap with the lightmap in it and multiply it over the diffuse map but not sure how to connect it all?

Oh and for bonus points, is it not possible to connect a spec map with RGB instead of a single channel?

Here is a pic to make things (hopefully) clearer...

Also the mathcolorblend node do some of the photoshop fusion modes. And looks like you can't have coloured specular with the standard material. Then i don't know how to use the advanced material

That's great, thanks!
