Do you know of some commonly used software that can generate IOR textures
we do not need a program to generate IOR textures, it should work with any texture, with any image, based on the gradation of dark and light, where dark adds IOR and light removes IOR - or vice versa, it doesn't matter, the algorithm subtracts from light to dark, this allows us to define areas with and without reflection on one object through the texture.
For example - a leaf of a tree, the leaf has veins that have no reflection, and another zone of the leaf has a reflection, this makes our picture realistic.
It is impossible for the entire sheet to have the same IOR value, this is not correct.
I’m not saying that your theory is not correct, I’m saying that we probably have an error somewhere in the work of IOR with textures
Please note that when switching IOR mode to Specular mode, the texture starts to work. If everything is correct, then there should be no changes in the reflection when switching different modes to IOR.
I tried a texture with 16 bit depth and the problem persisted.
I also observed problems - when I tried to adjust the IOR through the texture in the color-correction and it did not work, RGB level 0 and level 1000 always gave reflection, but the texture at RGB 1000 was absolutely white, and at RGB 0 it was absolutely black. The reflection was of different strengths, but it was a reflection. Although, within the maximum range of 0 and 1000, I should have had maximum reflection at one value, and complete lack of reflection at the other.
The working range for the color corestore was approximately 120-180 in the RGB, all other values of the RGB multiplier simply did not work, there was no texture on the reflection, it was just a mirror with different reflection strength
Also, if you check the Invert checkbox on the texture, then the card starts working - this also indicates that the work is incorrect, because the invert should swap the reflection and its absence, and not turn the texture on and off.
You need to make tests with a simple texture, with 3d max procedural maps everything works fine, the problem is in raster textures
Another oddity - texture in IOR through color correction with RGB 500 - has the correct reflection pattern, if you make RGB 700, then the texture is perceived as inverted for reflection, but the texture itself remains the same, but the texture itself has become brighter, but not inverted, why is it in IOR perceived as inverted?
I think we have obvious problems with the perception of the range of brightness of the texture, somewhere there is an error in converting the brightness of pixels to IOR values
