texturing/rendering help

Postby thomwickes » Wed Dec 13, 2006 3:24 pm

Hi there - rendering my first realflow scene - I exported the mesh with speed map texture thingy on it.

anyway - All my renders look weird. I've tried several textures now, and It still looks odd. At the moment, the best thing i can think of is to crank up the motion blur and animate the camera to disguise it a bit.

here's where i am so far...

You mean shaders? In any case I would turn down the reflection and crank up the opacity.

Personally I tend to cheat FG & GI with ambient occlusion and clever lighting, especially when animating.

The sim looks pretty good to me, perhaps a bit out of scale, but close and nice.

Looks really nice - as Ls3D already said use ambient occlusion, render in several passes,... so you can tweak it in the post.

Reminds me on the movie "Shining"

How did you render it?

ahh great,

thanks for advice and especially the compliments - put a smile on my face - I actually had 'the shining' in mind when I did this - I'd like to try the shot with the blood coming out of the elevator too.

I'll definitely try and add an occlusion pass - you think the render layer occlusion default will be ok?

Also, by cranking up the opacity, do you mean make it more or less see through?


Thanks

Thom

p.s.
Yeah, I meant shaders and not textures - schoolboy error :)

Hard to say - it depends on your scene settings,...
I use normally the Mental AO-Shader. And tweak it until i'm happy with the result.

It wasn't really a well planned render really - 3 point lights emitting photons (i forgot to turn this setting on for the rest of the lights, so its bright at the start and dark at the end) I used the "ProductionRapidMotion" mental ray preset, with Global Illumination and Caustics turned on.

I used the Denfo surface of ice texture for the blood - I removed the bump map, and changed the colour/transparency ramps. They're tartan originally - I made them V ramps and coloured them red with very subtle changes in brightness.

I'd be happy to share the scene if anyone wants a look.

If you want, you can email me the scene to take a look on it on.
I can also upload it on my ftp so everyone can take a look on it if you have no possibility to upload it.

That sounds good - I'll email it over tomorrow - I don't have the scene file with me today, and no internet at home at the moment so I'll bring it to work and email it over. Is the realflow mesh completely in the maya scene? or does the scene file still reference the mesh .bin files?
