Title: How to create an "infinite" desert like this?
Post by: Basshunter on 2022-04-11, 18:05:12
How would you approach the creation of an "infinite" surface like a desert with no visible mountains on the background?

This a situation where having a tool like the Vray infinite plane that could be mapped with some displacement map would be of great help. Since we don't have anything like this, I'd love to hear how you would achieve this effect.

By the way, I've tried using a really big plane in the past for this kind of scenarios. However, this creates some annoying issues when you need to zoom extend/out, specially when the main object of the scene is very small compared to the big desert plane.

You can set whatever render dimensions you want for a plane and then a map a tileable texture to it (set the render multipliers)

The rest just appears to be an environment fog/depth

Not sure what the purpose of this parameter is but in my case, increasing it also increases the size of the plane in the viewport, which is not desirable. I don't want to end up with a super big plane in my scene because of problems I mentioned before.

Edit: Apparently this parameter doesn't prevent the plane to become extremely large in the viewport while rendering is going on. Once I stop the render, the planes size comes back to normal though. Not ideal IMO, since having a super large plane in the viewport creates some problems when zooming extent/out.

I wonder why Corona doesn't have this simple tool yet?

The Plane stays 100x100cm or whatever you set the length & width in the viewport. The Render multiplier only scales in the render. Are you adjusting the value highlighted in blue?

Yes, I'm only touching the value in blue. Would you mind running this test again but this time having Corona interactive render in one viewport and perspective view in the other? In my case, the plane becomes huge in perspective viewport while interactive rendering is running and only comes back to real size when I stop the render process.

Just tested it, yep that happens to me too. I never use interactive rendering in the viewport, certainly looks like a bug or something.

Thank you for testing it out. I'll report it.

That's been reported since V1, when IR was introduced. IIRC devs said that this is nearly impossible to fix, because of... 3ds Max.

😕 If that's the case, why are we still missing a simple "infinite plane" tool? I really hate seeing V-Ray going faster in terms of development and feature addition. It used to be the opposite.
