Hello..I am trying to make my own preview for the material editor, does anyone knows about a topic that covers this?

If not...I make a preview scene..teapot with two lights and the teapot material is 100% white and I gave it some projectors. When I load the scene into material editor the scene works fine and when I put a basic layer the teapot changes and so on BUT...there is too much noise and even if I set the preview options to 6 in quality and 6 to bounces still too noisy (a little better though) but It is not by far the quality that I get with the allready supplied previews like, arroway, default preview, ect.

How can I make my preview clean or almost clean in factor Quality 6 or higher and bounces 6 or higer.

Should I render my scene?

Should I make a preview in maxwell studio?

I will really apreciate any help. Thank you.

You have to optimize the scene you use for the preview as much as possible. Otherwise ofcourse it will take longer to render.

Basically the preview scene is a normal mxs file that sits at the preview folder. It will have a material called "preview" which is the one that will be replaced at the mxed when previewing.

To make it faster you should have one or two low poly emitters, keep geometry simple and maps small (in the preview scene of course). Delete all unused materials and not needed objects from the scene. Optimize it from studio. As with normal scenes don't use 100% white surfaces (even though jomaga tested it was not as bad as with previous versions I wouldn't go higher than 220,220,220) cause it's unrealistic and produces more noise.

Thanks Mihai, Gracias Fernando:

What do you mean with optimize in Studio? I do have a material called preview but it is 100% white...maybe that is why it gets too noisy.

I think it was you Mihai that posted a very nice explanation about Glass, I am making a light source inside a glass bubble, no matter how much it renders that I get black spots in the glass (noise) do you have any recomendation making this type of glass? Should I deactivate indirect caustics?

It is like I had a light bulb. Sorry about asking another question.

It doesn't matter which material has the preview object cause it is replaced by the tested material.

I prefer to take the scene into studio because a mxs translated from plugin usually adds an extra camera and maybe other things which are not needed.

About the backlight illuminated glass... it usually will take more SL to get clean than the preview will render. If you have used SSS in the tested material remember to use RS1 for the preview cause RS0 does not take sss into account.

I made some preview scenes to check attenuation and sss. Maybe they are useful. The last ones are back-illuminated with a mxi:

I will take this into account next time.
