Hey there guys,

Is it actually possible to use Physical Sun + IBL (HDR file) in conjunction?

I've loaded a HDR and my physical sun went dark. I'm kinda lost.

Thanks for any replies, in advance.

Easiest way is to use sphere with HDR and add ND=1 vacuum layer next to emitter. Then set sky intensity to 0.

Oh thank you Alex P. That'd be a good workaround.

Though, I've always thought that Maxwell was able to use IBL's and physical sun together. Can't remember where I read about that.

In maxwell 1.7

We are wainting for resurrection ever since.

HDRI SKY (PRESUMABLY SUNLESS) + AN ALIEN SUN (WITH NO HAZE) IS A DUMB IDEA, Y'ALL STUPID.. LATERS.

btw. Painting the sun spot in PS gives fastest renders, but it is a bit tricky to guess how bright the spot/haze/sky should be.

It's dumb idea to use sky dome + sun - it gives wrong color. With physical sky setting sky intensity to 0 doesn't change sun color and works really good. Of course you need to keep haze on HDR and match sun position.

Thanks for the tip.

Anyway, would be great to have IBL + Sun feature without workarounds.

I've noticed that that workaround has one disadvantage. As dome emitter is big it takes really hard to render small light next to it. I had to render twice.

Yes, you're right. I left over weekend one small house to render with this technique and it reached sl13, I was like wtf? I have use maxwell since beta and this has been the slowest render ever.
I could even say that it triple render time.
I hope we get a real solution
