Help with XSI render map tool. (Forums : 3D Modeling & Animating : Help with XSI render map tool. ) Locked

Hi,

I'm just learning the ropes with XSI. Al of my attempts to render map a model turn out black. I have imported a couple of different characters to convert to source models. Whenever I try to make a tga file with render map, I just get an all black image. Hopefully somebody can help me.

Thanks

This may be a stupid question, but do you have any lights in the scene? The first thing to do in XSI is to turn down Ambience (to black) and delete the custom scene light. Then you can start with lighting your scene. And you need light(s) for baking!

What material did you assign before the bake? Here is my superquick list of how to bake diffuse in XSI:

1. Click on the model
2. GET (menu) Property UV -> Render Map, chose: unique UV's
3. super sampling 2, hit regenerate Maps

Get the map from the folder you saved it to, create a new CONSTANT material and assign the baked texture. If you bake any additional objects in the scene, assign the old scene material again. Otherwise the lighting info from the constant will show up on your map.

'ello moose, 

Do you mind sharing any screenshots or the model itself, or even part of the model  (.scn/.xsi/.dae/.obj/.fbx/.emdl)? I can think of quite a few different things off the top of my head that might cause a black map, but a lot of it depends on the model and your settings (material, lights, the type of map you're trying to bake, how your UVs are set up, if your normals are inverted, possibly duplicated faces, the virtual camera settings, etc).

Thanks for the answers guys.

I will try to get a screen shot up tonight.

Basically what I am doing is: I exported a model from Daz Studio in the Crosswalk (.dae) format. I reduced the polygons to below 8000 for use in the source engine. I am trying to unwrap ( if that's the right term) the texture into a tga file so that I can use it to compile the texture for a source mdl.

I am working only with headlights, so maybe that's my issue right there?

I am following this tutorial if this helps until I get a screenshot up.

Thanks

Ok,  so because I'm a new member, I cant post a picture.

Here's a link to flickr where I posted a screen shot. (sorry, I had to remove the www)

It'll take quite a few screenshots or the model itself to get an idea of what's going on (render settings, uv layout, etc)

Honestly, I think he just doesn't follow procedure.

If you have problems with it, google or rather youtube XSI baking + rendermaps  or similar. You should get to a cartoon tutorial, which has a similar character than yours. If you follow the instructions there your character will be baked in 1 minute. If you then remember what I wrote above (about applying the material/texture), everything works out!

SinKing, I have googled until my eyes bled, and I can't find anything.

What I did figure out on my own is that it has to do with the Daz 3d texture. I imported a Makehuman model ( which looked awful) and I could render it no problem. As for tutorials and procedures, I posted a link above to the tutorial that I followed. I followed it exactly, and when it gets to the rendermap step I get a black render. The tutorial is 2 or 3 years old, so maybe something has changed with the newer versions of DAZ?

I can post more screenshots once this site allows me too. Should be a week from my original post. the model I posted is not the one I was working on. I just imported it as a crosswalk dae file.

Thanks.

It really could be a number of factors; even a UV island that is too small has caused black maps in the past.

What type of map are you trying to bake? Perhaps you can use a sampler instead, or bake in xnormal.

Thanks Cryid. I'll try out xnormal.

I am trying to make a tga to convert to a source engine character. I really am just learning the ropes so I think the right term would be unwrapping the texture to re-apply it after I export and convert the model in an mdl file.

I seem to have everything else pretty much figured out, even the rigging. Just can't get those DAZ models to show up in a render map.

This is the tutorial I was refering to. If you bake like this and then apply the new texture to a constant you will get good results in XSI. If you wanna use it in HL2 that's another issue, but it should still be the same map. Did the model have no (diffuse) texture set, or why are you compiling for Goldsource in this difficult manner? If you just follow that tut, baking will work. Can't help with the rest.
