Wait, I was referring to a CRT screen

I think this clearly tells how old you are :] For me it's the same - whenever i see similar question, CRT screen always springs to my mind first, eventhough i didn't see such screen in the last decade.

Topic related question - if light material is used with "emit light" being turned off, is this still counts as light material, or as self-illumination in terms of GI calculation?

Half-joke, half-serious solution - mouse jiggler.

I think Corona 8 HF1 is the latest release. There was no daily build after that, so perhaps it's worth to install it instead of DB?

If it's on Windows, then you can use symlinks and move material folder wherever you want. Not sure if Mac has something similar.

Thank you Marcin, but i kinda already knew the formula. The problem is i don't know how to apply it to the texture image. I guess the most logical way would be to build a LUT, but again, no idea how to do that. Anyway, i'll try to dig deeper and see if i manage to find the answers. Appreciate for your help!

Corona physical material gives you an option to chose between specular and IOR modes, unfortunately this functionality hasn't been ported back to old materials, like legacy, or skin, so i'm looking for a tool to convert specular textures to IOR. After some research i found this topic by Dubcat. Since i'm using 3ds Max 2016, i don't have access to OSL, so i had to use his LUT file in Affinity Photo to convert textures externally (which is preferred method for me anyway). The problem is, that i couldn't manage to get correct results with it - it's either i don't know how to use it properly, or Affinity treats this LUT somehow differently.

Then i found this tool by Mohammadreza Mohseni, but virus total flagged it as malicious, so no use :/

At this point i'm out of ideas, so any help would be greatly appreciated.

It's easy to get caught and get annoyed by this behaviour, but when you think for a moment how displacement should act when it meets hard corners, it's not as easy to find a proper solution as one might think.

I think you already have been told how to fix it - just add support edges near the corners and between these edges all displacement will be perfectly perpendicular to the surface.

[..] but it shouldn't work like this...

It not always worked like this. It used to displace perfectly perpendicular to surface, but we had tears in geometry wherever there was hard edges. Needless to say, people weren't too ecstatic about this neither. It's a compromise and i think it's much better to have current solution, than to have to deal with tears.

Most likely it's normal. RAM usage depends on scene complexity - the heavier the scene, the more RAM Corona needs to render it. If it only takes small portion of available RAM and renders fine, then you have nothing to worry about, the trouble begins when there's not enough available RAM.

Corona version - 8 HF1

CoronaWire does not work correctly on meshes with displacement. Only partial wireframe can be seen here and there. Situation improves slightly when smaller image is rendered , or when thicker wire is selected, but still it's impossible to get decent result.

IIRC it used to work just fine in older versions.

You're welcome. I don't use many scripts and most of them are related to modelling, so i don't know if that's relevant to you.

You can look for various scripts and tools in this forum topic: Personally i use and like Prune scene script.
