Logged as a feature request. Probably cannot be expected in V5 as it is going to be mainly a maintenance release.

Nice it's been considered AND you guys have a feature request list. Maybe poke the Vray guys to make one as well, or at least if they have one, to be a bit more open about it :)

Probably a little off with this but the random brick thing may sort of work like the using of Max's tiles to create a procedural brick texture. It looks like some of the bricks in that example are cut in half. Not sure if anyone knows this method (probably do) but you basically randomly place a brick texture which features 2 halves of a brick with mortar in the middle and then a full brick underneath.

Then using tiles to generate a random series of black and white alphas to show/hide the textures. So perhaps he has something similar to that? As its been said he may be using a grid to generate and then within that he is just randomly overlaying the texture.

Probably isn't how he is doing it..., but its a method anyone can use to create a totally procedural brick texture with just 6 different brick maps. Pretty basic, but it works fairly well. Plus since its Max tiles doing the distribution you can have really high res or low res maps in the slots so its pretty customizable.

Been asking this for a few years over at the vray forums. Hopefully the fact that Karba did it and you guys are asking for it will spark the flame to implement this both in Corona and Vray. Here's hoping :)

Youd hope but we have been asking for geopattern, dslr tonemapping and a PBR material for a long time too

My first request for that was somewhere around A4 or A5 stage of Corona, so they are not really keen on that

Also that would be a great feature, but isnt this already possible using OSL?

I installed Fstorm demo just for this feature alone. Didn't like Fstorm itself at all, but random tiling is just some magic, really! Definitely would love to have it in Corona. The only downside (a big one), that it doesn't work with displacement.

Im yet to try it. Could you bake the randomised map down to file like with procedural maps or is it created at render time?

Hm, i could try that, but is there any point in doing that? The main benefit of tiling randomizer, is to cover unlimited area with reasonable resolution texture. By baking to texture, you'll just loose that.

The point would be that you could generate a big enough randomised map to cover the area you need. then use that baked map in corona only using fstorm to generate the large scale seamless texture.

You can do that in photoshop, with much better result. Also texture rendered by Fstorm wouldn't be seamless, so you'd have to render reaaally large textures, which is hardly practical. Anyways, i did the test and the answer is YES and... NO. You can render it...

1. from material editor, but it's ruined by strange artifacts
2. normally with texture assigned to a plane and with neutral lighting, but the demo has watermarks. Also it looks that there is some tonemapping applied, even if i explicitly turn it off (might be that i'm missing something there)
3. as a render element, but for some reason it has applied strange gamma (could be because it's demo, or because i'm missing something)

In any case, i don't see a point to dig into this further.

+1 to have that in corona

but as for now max users starting from v2019 can use OSL Randomized bitmaps
