Error when converting Corona to VRay

[illahi_brohi]

Hi,
I have V-Ray 6 Update 1.2 [6.10.08], and i don't want to install the nightllies version [it's not the official version], so what can I do!?
Can you Share the (vrayutils.ms) file, so we don't have to install new version on a bunch of PCs, for replacing this file only!?
Thanks in Advance.

We can't share the vrutils file, it may risk erroring out in other places, from time to time.
It has to be delivered with the V-Ray build it's intended for.
You can safely download stable builds (not nightlies!) as they've gone through QA and are as safe as the next official release.

Thanks' Lele for the replay, this error presents since Corona 8, 5/2022!! which equal V-Ray 4.3!

I Tried using 6.10.09 converter on 6.10.08 and I got The Following Errors:
1- vrDistTex.objects = inTexture.nodes Error (if the node is <deleted>).
need to check if all nodes in the array are valid nodes.
2- vrm.refraction_fogDepth = units.decodeValue formatted Error (Runtime error: Unable to decode value: "inf", In convertFrom_CoronaPhysicalMtl(), cpm.attenuationDistance = inf.0).
I don't know at any stage the value become inf.0 (it's a float value), but units.formatValue can't be applied to it! need to be replaces with 0.0.
This Errors not related to V-Ray Version.

I'll poke the relevant dev about the first error (but you can fix it by removing any deleted node from your Corona distance textures.).
For the second i will need the material in question and the otherwise empty scene it lives in, as it seems the standard max method to convert scene units (which we need because we always express the value in cm) is throwing up an error with the value encoded in the Corona material, which shouldn't happen.
To fix the latter error, you can try and pick a much bigger display unit scale (from mm to m, f.e.) and if at all possible (but this will rescale your scene) a more granolous system unit scale (meters, cm, instead of miles or KMs), to close the gap between the two.
For example, with system unit scale set to 1 mile, and display unit scale set to 1/100th of an inch, the method fails with a value slightly above 33000.0 in the Corona material's SSS Radius, which is still a very big and unlikely entry in a shader.

Thanks Lele for the replay, it's all in CM-M , but this inf.0 value came from old model (i think the value become like this when converted from CoronaLegacy to CoronaPhysical).

The Converter should Solve or Ignore these issues, Better to be Solved by the converter because it's easy to handle.

I will need the scene that errors out.

for the distance texture bug, the issue is seemingly a bug on our texture's side, nothing to do with the converter. (VMAX-13603)

[illahi_brohi]

This file has both error messages,

[^Lele^]

thank you!

I know of no way a user can input a value of inf into a spinner.
What converter did you use that produced this result?

regardless, the fix is implemented as a clamp to 1e12 (0.0 for V-Ray wouldn't work like for Corona.) for incoming values. (VMAX-13604)
It'll be in the stable builds soon enough.

I don't remember exactly when that happened (it's an old file), but I think it's the "corona converter" (I'm not sure about that).

Would you have the original Corona material? It'd be very helpful for internal investigation.

in Corona Legacy Material you can find some "inf" Spinners, like in the image it shows the "Water lvl" min max.

in Corona Legacy Material you can find some "inf" Spinners, like in the image it shows the "Water lvl" min max.

I know what the limits are, but it's impossible to manually input the value.
Hence my request for the original material, before being converted, which i renew.
