Rendering Issue? Maybe problem with model.

[wndrboy2k3]

Hey, sorry to have to write in the general forum it seems to be the only one I can view. Anyway, I have just purchased lw 2.3 and am importing my first character into the editor. Below is the maya rendered and wireframe version of the character to demonstrate what it should kind of look like.

 

 

 

This is how it's looking in the Editor.

 

 

Is there something I am doing wrong? I made a few props and they worked just fine.

 

I'd really appreciate any feedback.

 

Regards,

David

The editor by default has bloom and HDR turned on have you tried turning them off to see if it makes difference?

Yeah, I had everything turned off, even shadows and it still looks really strange. I mean i don't expect a game engine to render like Maya but i've seen other people's work and it does not look this bad.

Dont forget to email Josh to get your group changed so you can access the rest of the forum.

 

 

Maybe its your material files?

It must be, because when I turn down the lights REALLY low, it looks quite nice. I checked my texture levels and they are normal, Having said that when I turn the lights up the shadows kind of go nuts on the especially the lips.

are you using a specular shader?

are you using a specular shader?

 

 

Right now i'm only using diffuse. I wanted to make sure that would work first. I've been searching for tutorials on this material editor for sometime now, no such luck.

try to change your importing pipeline.

if you are using OBJ format and then OBJ2GMF, try FBX format and then FBX2GMF or inverse..

-Add your normal map and specular map to the material. There are lots of examples in the SDK of materials with a bumpmap.

-Disable bloom and HDR.

-Use a darker ambient light color.

The reason for all, is very visible. All of the ambient settings of the Maya(lights, Ambient Lights, textures..) is very diferent of the engine.

 

How the josh says, you need create a ambient light dark in the engine, as this in Maya. Add a specularmap, to dont burst the lighting in model, and disable the bloom and the Hdr, which the Maya dont have.

[omid3098]

if it's just because of bump and specular, so smooth quality in real-time maya/max viewports (not even final render) looks much better than LE's realtime.. or there are other things behind the scene, that I don't know about them?

?? i dont see much wrongness - since the make-up seams to be a little misplaced in your render too. In fact i think it looks quit nice for just a diffusemap. If the model does has holes, i would suggest to try only one pointlight and add cullface=0 to your matfile - if this helps with your shadowing issue, close all holes the model might have. Wild guessing ahead.

 

PS: Oh, and reweld vertices after triangulation (smoothgroups etc.).

The mesh is completely closed. My problem is with the crazy shadows on and around the mouth. When the model moves they go even crazier jumping all over the place. But i did fix it just by rebuilding the mouth geometry. It's pretty much the same I guess just smoother. Strange.

Directional light shadows are designed to light an area of kilometers. You are not going to get high precision shadows on something as small as character facial features, with this scale of lighting. You can decrease the directional light shadow distance to have more detail in a smaller area, but you will lose shadows in the distance. You can also increase the light's shadow map resolution. This problem is common to any real-time engine that uses shadow maps. Here is an example from Crysis:

ok now josh... did you really think you'd get away with flashing that screenshot past and not offering some sorta explanation as to where it came from (looks like the interior of one of my subs )... and showing maybe a few more of em... now did you...

Like i said I didn't think it was a problem with the engine as I have made many other props and they turned out just fine. It just seemed kind of odd that this particular one was so different. I've rebuilt the mouth and seriously the result is 100x better! Now to write an SSS shader.
