Max Projection with opacity

Jtd18801

Hey guys looking for a little help here. I'm pretty sure this can be done but I just don't remember how to go about doing this.

I'm trying to use Max's render to texture feature to get a tree onto a flat plain as a Diffuse and Opacity mask. the issue I'm running into is rather than rendering out just the leaves the renderer is ignoring the opacity mask and capturing the entire polygon the leaves sit on.

Is there a way to have the render to texture project with the opacity mask in mind?

Thanks

Sorry, but no I think. We've tried it at work earlier, and also couldn't get it working.

RTT doesn't support opacity. However you can RTT the old fashioned way... point a camera at the model and render it. As long as the lowpoly projection is flat, it'll work fine.

Oh nice workaround! Unfortunately that couldn't work in our case, but still useful trick.

Hmm. Why not?

It works fine in this case I was talking about me and my mates at work. Because we wanted to bake to more complex objects than planes.

Thanks guys, I was thinking that was going to need to be the work around. Hopefully the allow it in a latter version.

it's not happening since the beginning of projection in max, so i kinda doubt it

anyways, you could bake with a blocking mesh and use matids or object ids or just bright colors to bake the mask
