Ground Projection: Corona vs. V-Ray

[kosso_olli]

I'm just bumping this thread to check if there was any thought put into this.

Yes, we're considering it, but since it can already be achieved with a host of other approaches, it's not in the top of the list.

Just out of curiosity: Which approach would you personally recommend?

Thanks for the trap, but I'm not getting dragged into this When the respective devs reach that part of the list, I will sit with the other guys and we'll decide.

Ok, too bad My point just being that the way to work around this issue currently is quite difficult and unless you spend 30 minutes to build some complicated custom setup that the average user probably wouldn't know how to do.
Anyway, happy to hear it's being considered!

[kosso_olli]

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

[matanov]

Nothing new, but it's surely not forgotten.

I can assure it is still needed very much.

Hi, I think the ground projection is now totally broken in the current release in following situation:

- Domlight with VRayBitmap Spherical HDRI Ground Projection enabled (e.g. 250 radius)
- Enabled "Lock texture to icon" in the light
- If the domelight has any z-rotation other than 0 the ground projection totally fails to place anything on a groundplane.

Can we just have it like in Corona please? I really am really struggeling to see how the ground projection has any use in its current state.

Also, there is a glitch in the UI now. The "position" label nearly intersects the checkbox.

Hey Jonas,
can you please send us your simplified scene where the problem occurs here :

to be able to take a look and investigate further

[JonasNöll]

Hi, sure but I think with 3 steps I posted you could just replicate it yourself, or are you getting a correct result?

[ivaylo.iskrenov]

Yes, I can not reproduce it on my side, so it will be better to take a look in the scene where it happens.

[JonasNöll]

Okay I will send you over something later

[JonasNöll]

ivaylo.iskrenov Here you can find a scene following exactly the steps I outlined. Note that if you rotate the view the teapot is floating over the groundplane. if the z-rotation of the domelight is set to 0 it sticks.
