Exterior wip

[Chakib]

Here is a result of PT+PT instead of HD cache

Always dots ! i think this bug is exclusive to the legacy build since the build daily updated for the newer processors doesn't have this bug ( fixed i think ), maybe i'm wrong.

This is sooo baad.... How does it look if you turn all the vegetation, grass, trees off?? Have you tried?

[michaltimko]

thats weird...

can u send zipped max file ? or its commercial project?

There is similar bug reported in Mantis, I'll look into it once I have the time. It should not be hard to fix.

No, will try this tonight

no it's a personal one, but the problem is the size of the file is very big

Now i did delete all scatter plants and trees and light in the scene and keep just the hdri as light source

result : very fast clean 15 min render

the trees and plants don't have opacity at all, maybe the cause is the corona lights and their effect on the glass material.

[michaltimko]

those windows...material (glass) is set to Solid or Thin ?

those windows...material (glass) is set to Solid or Thin ?

They are thin since the solid doesn't work good for windows.

the glass windows object is not one face, should i apply the thin glass to one face object to get it work good or it's not important that i apply it on a "box" objects ?

[michaltimko]

thin is ok with box...

[lacilaci]

I'm using single sided faces and twosided material... However let's hope keymaster finds some time soon to get us around this issue and if it would improve performance aswell it would be awesome :)

Looks like I've fixed the bug ;)

You mean with VCM ?

will test it now and see the result ! Thank you Ondra !

The bright spots when using opacity/doublesided glass

[Chakib]

Ok, here is a test render that i did for the three modes :

Bidir : 37min
Progressive : 42 min
VCM : 1h16min

No Opacity here !
------------------------

Bidir :
- Fast render start
- Fireflies everywhere, it's chaos !
- Ground material is black ? weird...

Progressive :
- Very slow render start
- Fireflies !
- Ground material is OK !
- Curtain materials is not affected by light... weird !

VCM :
- Little bit slow render start
- No Firelfies ! ( maybe i'm wrong but i see some little ones on floor and walls... maybe i should give it more time)
- Ground material is black again ?


Conclusion : VCM is doing a pretty good job here but the noise needs more time, i hope it will be faster than now and also the ground material here i don't know what's wrong with it since it renders good in Progressive mode.

Next test : Trees with/without Opacity.
