Sloowwww render in v-ray

solo

Unfortunately in my experiance one needs to apply the textures again and set up the render from scratch between versions for it work again.

I use an i7 for rendering so my render times will be probably a lot faster than a quad, so please do not expect your times to increase too much between versions as your scene is very heavy with lots of complicated lighing algorithyms.

If you are able to upgrade to the latest version and adjust the scene for render, I will be glad to render it for you to save time.

no i wont be able to upgrade and I dont wanna lose that much more time .... thanx for your help, ill try to delete some lights as this seems to be the biggest source of problem!

thank you!

tommymartel

last question

I achieve to setup my lights so the render dont take weeks, but now i gotta get rid of those white dots, is it related qith light cache or sumthing ?
can you tell what it is ?

thanks again now I fell im getting somewhere

This thread as ASGVis is interesting in regards to lights and render times: http://forum.asgvis.com/index.php?topic=5208.msg28183#msg28183

I've seen them bright artefacts before, but I can't remember the cause. If you search the ASGVis forum you should find posts which relates.

white dots= pixels with value beyond 255 (very very bright pixels)
solution: in "Color Mapping" check "Clamp Output" and "Sub-pixel"
Good luck!

tommymartel

ok i got rid of the dots but now i got those spot on my white materials ... is it related to caustics? i tried to find answer but i coulnt....

Thanx thomthom for the link, very helpfull, damn there is so many things to learn about vray

thomthom

Could either be because you don't have enough samples for your Irradiance map, if that's what you use. And/or it could be that your Adaptive Amount under Image Sampler is set to 1 - if so, set it to 0.85.

What setup do you have IR+LC?

thomthom

hmmm... do you have caustic enabled? (not the GI caustic, but the one under the Caustic section?)

tommymartel

i think it was my adaptive amount in image sampler... was set to 1.... and no i dont have any caustics on

my samples in irridiance map is 20

I use IR+LC

now im doin it with another .visopt i htink its gonna be ok!
thank you!

thomthom

The Adaptice amount is best set to 0.85 - always. Check this value before you render.
