Hi Guys,
just some questions i have
1) before the update of vray, the noise was controlled under the qmc sampler by scaling from 0.2 to 0.001 for fine renderings. In the new vray,under the DMC sampler, this makes no difference anymore. It seems to have moved to the image sampler settings. is this correct?
What is the difference now between them? It would be great to see a manual of what the settings under each item does....like how it effects the image.
2) When using a rectangular light, should ignore lioght normals be checked or unchecked...what does it do and what is a light portal?
3)When using rectangular lights, you can make them invisible or visible depending on if you want reflections on your products. This is a great feature to get nice highlights on your product but quite ofte the light gets in the way of the camera scene when rendered. Is there a way to get the light to reflect buty not be rendered?
4)Under image sampler, does the image quality become better or orse when increasing the max subdivs?
5)Under adaptive subdivisions, the standard presets are -1, 2. is that a low or a high setting and what would you aave to change to make the image quality better or worse.
6) Under DMC sampler. The default min samples are 8. Would increasing this be better or wose for the image quality.
7) Under IR Map. Should randomize sample be on?
What are the 2 reflection and refraction slots used for in the environment tabs? Why would you put in a background image but get another reflection....wouldnt you do that under the material section?
Sorry for all these questions but every where you read you just get suggested settings by people but it never explains the basics of things like, the higher or lower the value the better the quality etc.
Anyhow thanks in advance
