symek Posted February 18, 2008 Share Posted February 18, 2008 (edited) Think of Mantra as RenderMan, Maxwell, Air and Mental Ray plus a nice volume renderer all wrapped up in to one seamless rendering interface and you are not far off the mark. The analogy to Maxwell is closer then most of us thinks if we consider this piece of fine Houdini's docs: Mantra 9.1 properties:Internal: vm_renderengine IFD: renderer:renderengine Default: (0) micropoly - Micropolygon scanline rendering (default). raytrace - All rendering will be performed using ray-tracing pbrmicropoly - Physically Based Rendering using micro-polygon scanline rendering pbrraytrace - Physically Based Rendering using ray-tracing only. photon - Photon map generation. viewpohoton - View dependent photon map generation. irradiance - Irradiance cache creation (partially implemented). metropolis - Physically Based Rendering using metropolis integration (partially implemented).

Andz Posted February 18, 2008 Share Posted February 18, 2008 I don't think maxwell uses Metropolis Light Trasport, but bidirectional path tracing. Indigo does use MLT. Quote Link to comment Share on other sites More sharing options...
soulsonic Posted February 20, 2008 Author Share Posted February 20, 2008 Hello all here an update with the smoking pipe. The shader is satisfactory but not realistic. I'd appreciate any pointers. I am using the materials smoke shader. I used to like the older version on h8 and below had more control in terms of controlling opacity. Thanks All -R Quote Link to comment Share on other sites More sharing options...
soulsonic Posted February 22, 2008 Author Share Posted February 22, 2008 Hello all here's an update! I will be rendering 3 hundred frames tonight hopefully I can post a short! -R Quote Link to comment Share on other sites More sharing options...
soulsonic Posted February 27, 2008 Author Share Posted February 27, 2008 (edited) Hello all this is a first pass render with the rain. Thanks to Miguels rain OTL. Any helpful comments are welcomed.

stevenong Posted February 27, 2008 Share Posted February 27, 2008 Hi, First of all, the rain drops are too big. Also, you should exclude the rain from the light's shadow mask. I feel the environment for the car's reflection can be improved. In addition, I will prefer the rims to be an alloy-type material, not shiny chrome-y metal but matte silver type shading. Good stuff so far. Please keep the updates coming! Cheers! steven Quote Link to comment Share on other sites More sharing options...
soulsonic Posted February 28, 2008 Author Share Posted February 28, 2008 Thanks for your good comments stevenong really appreciate it I will certainly make the raindrops a bit smaller and also add a bit more of them. The reflections are something tricky but i will add more. I had a matte rim finish but I chose the black metalic type.- -R Quote Link to comment Share on other sites More sharing options...
MIguel P Posted February 28, 2008 Share Posted February 28, 2008 Thanks for your good comments stevenong really appreciate it I will certainly make the raindrops a bit smaller and also add a bit more of them. That would definitely improve it. I would also stop the car rotating (that's what seems to be happening) and move the camera instead.
