GRACIAS OBRIGADO THANKS !!!

Thanks for this article, very interesting. I have resolved many questions I always wanted to know.

Thanks for the kind comments

Hello:

it's work in vray for sketchup?

Hello Pedro,

Despite there are little distinctions in some parameters, this article is a true for all the V-Rays. The V-Ray raycasting principles, described in current tutorial, are applicable in V-Ray for 3ds Max, V-Ray for Maya, V-Ray for Rhino, V-Ray for SketchUp, V-Ray for Softimage, V-Ray for Cinema 4d, and V-Ray for Blender.

Hello RenderStuff,

I have a problem for quite a while and I hope you can aid me. When I try to render for the first time after opening a scene, the render, computer, everything goes unresponsive for a while (like 5-8 minutes) when it calculates the static raycast in V-ray. After that, everyting goes to normal and continues rendering. This happens only once after I open the scene in 3ds Max. If I close 3ds max and open the scene again it happens again. The Raycast is set by default values. If I merge the objects into another blank scene, the problem goes away but only for the first 2 or 3 saves. Can you give me perhaps some advices?

Thank you!

Hello George,

This is definitely a lack of RAM for the scene you are trying to render. You should either buy a few RAM sticks, or bring the optimization into your scenes creation approach. Make sure you have adequate polygon count for your 3d models, use the Instances for objects in scene as much as you can, check if the used textures number and resolution are optimal.

As for why it happens only the first time, it's simple. The data filled in memory only once; all the following times the much of data stays ready to use

Thank you for your prompt and efficient answer

Well..things make more sense now My scene is very heavy indeed. I excluded this possibility for a while because I thought 8GB RAM was enough. Now that you told me, I rechecked the RAM usage and it goes suddenly to 99% when is raycasting. I will try to do some optimization maybe some vray proxys and instances as you suggested.

I also read your other tutorials, and I have a small question regarding gamma 2.2 workflow which I use it for some time but I still have some gaps. I will post it there.

I hope I'm not very annoying posting a lot of questions.

We have recently decided to make the hardware upgrade and found that the DDR3 memory is very affordable nowadays. The $50 can bring you next 8GB of RAM. If your system works with DDR3, of course


George M., surely ask your questions in appropriate tutorial. If you will have a question, which is not related to any of present tutorials, feel free to create a new discussion

outstanding explanation......gud job )

Thanks for these Vray tutorial, help me a lot!!!

you're a genius!!!!............thanks.
