Order of Actions

[cyhiemstra]

Hello all,

This is a very broad question perhaps inviting a spread of responses.
Ive got quite of bit of experience with graphi design and even sketchup but Vraying is still slightly new to me. Ive always been very interested in process and efficiency when doing these things though. SO i want to throw this one way out there:

Q: It takes me about an hour to run a render just to find out the materials are wrong/ lighting/etc.

When modelling 1 room and using a library of materials what really is the best order of events when building an image? Mine is this
1. model the room
2. apply materials without editiing
3. run a full render(otherwise i dont see anything properly)
4. adjust.
and repeat 3+4 which is taking hours, days, weeks at the moment.

Are there tricks to correctly mapping textures first time around (rhino rendering viewport only shows 1 or 2 materials and often the texture mapping is different from the render result anyway).

Thank you for your time.
Chris

Edit: I just discovered the right click on render to render part of the scene, these are the types of tricks i need! please share your thoughts

Re: Order of Actions

Best thing to do is probably just to lower all your settings. I have a test visopt that I use to render quickly to test materials and lighting etc. Basically, I use only one engine for indirect illumination: Irradiance Map. I then lower the HSph. Subdivs and lower the noise thresholds for the image sampler and DMC sampler. And lastly, I reduce my output size.

The quality should be good enough for you to see many anomalies yet take a fraction of the time to render.

Also, when rendering, use the track mouse while rendering button to render only specific regions of the image. That way you can quickly see if a material is rendering correctly.

In term of the UV mapping, you should control the repeat option through Rhino texture mapping instead of V-Ray material editor. If you use the Rhino texture mapping you will have same uv mapping in the viewport and in the render.

Re: Order of Actions

Thanks for that reply- the best way is then really to be rendering on low settings. I will put a settings file together which does this i just feel like its taking far too long.
