Dome light with ground projection: Environment above horizon is incorrectly scaled

[kosso_olli]

I see. Thanks!

This is where the term 'radius' for ground projection is confusing.... It should actually be called the Dome Capture/Projection Height. It should be a world-unit value. So typically it should be 150cm - 170cm depending on where the dome was captured.

I think an additional Sphere radius or even a rounded-box projection could be very useful for certain situations, Particularly in city locations where there are tall straight buildings next to vehicles... the dome projection does really not work well here and we often have to build up geometry and camera-map textures back on to get reflections working correctly.

That's what I am doing right now to get it working properly. The reflections are not believable otherwise, especially on black cars where you can see everything. Is quite time-consuming, though.

No, the sampling is a different thing. But I've noted your request and we'll try to figure something out.

Vlado, any news on that front? I am curious to try things out if needed.

Not yet, I'm afraid. Still stuck on SIMD-ifying the V-Ray SDK.

Well, whatever that means, but I guess it is important

[kosso_olli]

Well, I don't want to annoy anyone, but is there some progress? I have around a dozen of car renders in a city environment, where this would make my life a lot easier!

[vlado]

Nope. It won't be soon, I'm afraid. Do not wait for it for your current project. You could try mapping some version of the HDR to actual geometry, just to get the reflections right.

Someone over at the Corona forum had a similar request. He posted some pictures and videos from VRED, where this is quite good actually. Take a look at this thread, it plays along with the ideas you had for stretching the environment for roads etc.

I'd also like to see this issue addressed. It's been over 12 months. Is there any update on this?

[kosso_olli]

Oh yeah, some fix for this would be very nice and most welcome!

[kosso_olli]

I would like to raise awareness for this again. A feature like this would be a huge advantage!

[kosso_olli]

I want to renew this request. This is so badly needed, I can not describe it. This is a major drawback, because clients easily spot the difference in the reflections compared to a photo of a reference.

[kosso_olli]

Just to bump this again, how is progress on this?

[kosso_olli]

I can not stress enough how welcome the new finite dome in V-Ray 6 is for our team! We have been waiting for so long, and now it is finally here. Thanks, guys!
