Hi guys …



I am new in this forum and I heard it is a good forum and there is a pro members here can help me , so I get here to ask you some questions please help me because they are very important to me !!



1 - in this page http://odforce.net/w…=mentalraysetup [odforce.net] there is a way to setup mental ray to houdini but I didnot understand anything .Example , setenv MI_LIBRARY_PATH ”/path/to/mentalray_version/platform/shaders” I replaced the path with C:\Program Files\Autodesk\mentalrayForMaya2015 . Is that right ?? and in the path I replaced there are no folder called platform !!! ,so am I use a wrong version of mental ray ?



in the picture the way I do the things in the page

















2 - when I setup mental ray can I use its materials and shaders we were using with maya and 3ds max ?? mental ray has a lot of shaders and materials we can use helpfully . and will MR render high quality and accurate such as rendering in maya or max ??



3 - what is ray3rc file ??



4 - can anyone tell me how to setup mental ray with video with full details because I am a beginner , very beginner noooooob ? so I need the way to noob man please !!!



5 - Can I setup V ray in houdini ? If I can , tell me how to do that with full details such as mental ray , please .



6 - Can I use V-ray materials in houidni ??



7 - Can I render fluids and particles and other dynamics in houdini with MR and VR ?



8 - Can I make fluid dynamics or any dynamic or anything and render it in LightWave render or MR or VR ?



9 - Is computer with : Intel Core i 3 and Intel HD graphics and 8 GB ram able to open houdini quitly well ?



10 - How to speed mantra render ? I make a simple mantra surface material and make reflaction and refraction and I put the sphere which I put the mantra surface on it on a gird with checkboard material and the render took about 20 - 30 minutes !!





I know it is many questions and my English is very bad but I know you will help me :blush:

I am very blush from you :wub: :blush:

Welcome to Houdini world!!!
Now man forget about metal ray, mantra itself a great render engine.
You definitely need a better graphics card. For pyro and flip you need more RAM as well.
You are using wrong settings for rendering which takes unusual time. For better answer post your file so somebody can have a look.

Welcome to Houdini's Forum.

Yes , Mantra is great and it's very very powerful (* 100) for rendering Volumetric like PyroFX (Fire - Explosion - Dust and … ).

But Mantra is a little complexer than Mental Ray , you should do some changes in the Materials to achieve your special result (like RSL programming in Render Man or 3Delight).

So the Best way is to render your Volumetric objects like Fire in the Houdini with Mantra and Render other objects in the another software like Maya via Mental Ray.
(Of course if you learn Mantra perfectly , you can do all in the Houdini with Mantra)

I didn't install Mental Ray , But I think you should buy special version for Houdini , because you don't have MR shader plug-in for Houdini in the Autodesk MR folder (Autodesk\mentalrayForMaya2014\plug-ins\Mayatomr.mll) !

About export Fluid Effects to another Software you can use VDB , But your software should be support VDB !

One of the simple way for exporting PyroFX to the Maya is to use Houdini Engine , But it's not available for Lightwave !

About your Hardware , it's good for Learning Houdini , But you should upgrade it later for big projects !

thanks you very much

well , is arnold able to render fluids , smokes and other dynamics ?


thx

I'm not sure about smoke(Pyro) but particles and other dynamics you can.

Anas Alaa
thanks you very much

thx

I didn't use Arnold in the Houdini , But it can Render Fluid Effects in the Maya very well , So I think it can Render PyroFX too :wink:

Yes , It can Render PyroFX too
