Maybe, but i think you should start new request for that. I'm moving this topic to resolved board.

Triplanar is not messing with aspect ratio. If you have non square texture, first you need to setup tiling correctly in the bitmap node itself and then triplanar will work as expected. It's not triplanar's job to work with aspect ratio.

@danio1011, similar reports has been all over the forum lately. Apparently it's some issue with the V8 dailies.

Unfortunately materials in 3ds max are system units agnostic, so if you importing materials in the scene that has different system units that they were saved in, then you will have mismatching scale issue. AFAIK it has nothing to do with Corona and it's the same for all renderers. Usually the difference is 0.1, 10, 2.5, 0.4 and so on, depending on the system units being used. It shouldn't be arbitrary numbers like in your case, unless you have some non orthodox system units setup.

You can make frankenstein map by stitching randomizer, triplanar and color correct to Corona bitmap, but that still would not solve the problem of adjusting multiple maps at once, not to mention that native bitmap users would be left at big disadvantage. I think that much better solution is to implement master control option in all those maps, the one like Corona color correction already has. It works great, is much flexible and doesn't clutter UI.

Material library has not been converted to the new physical materials yet, but eventually it should happen. Meanwhile you can use library materials as they are, or you can convert them to physical with Corona converter by yourself.

If curtain blocks most of the light that's coming to a room, then indeed it can negatively impact render performance. Luckily, in Corona there's no need to render twice to exclude curtain from affecting the lighting. You can do this by assigning rayswitch material to the curtain and plugging your old curtain material to all its slots, except GI. You can read more about rayswitch and its uses here:

Texture file format doesn't matter, heavily compressed JPG will take as much RAM, as uncompressed TIF. What matters is resolution, bit depth and number of channels.

Edit: here's the confirmation from one of the devs:

Also "Include" model would be very useful

Include/exclude is already possible.

« on: 2022-01-14, 10:10:36 »
Apart from occasional bugs already mentioned, there is also performance difference. UHD tends to be faster than 4K on low core count CPUs (e.g. 4-core i7s), while 4K cache tends to be faster than UHD on higher count CPUs (e.g. 16-core threadrippers).

That's useful information. Thank you!


I think you would get much faster response if you'd submit a ticket through the support portal:

[Max] I need help! / Re: Find displacement materials
« on: 2022-01-13, 09:41:54 »
You could use batch material edit script to disable displacement map slot on all materials and then enable it back by hand on the materials that you want.

Or you can simply use rayswitcher material and leave the GI slot empty.
