Roeland.
Firstly, that doesn't work. Secondly, the stupid sharp shadow issue makes even using a normal a waist of time.
No normal
Normal at strength 1
Normal at strengh 10
I don't mean to be negative, but is this another limitation of the software that is not going to be fixed until a version I have to pay extra for?

Increasing the power definitely works in the standalone version. What is the version of the plug-in you are using? Maybe the plug-in clamps the power value between 0 and 1.

It is the Lightwave plugin. I just check the code and I think that there is not clamping in the power value between 0 and 1. Anyway I am going to test it later.

Yup, just tested an exported OBJ. Works in Standalone, but not in the plugin.
However, both still have the hard shadow problem. What's happening with that?

Are you using the last plugin release (1.36.0)?

Ok. I have found a bug in the Texture Image node that could break the texture power value. I am going to fix this issue for the next release.
As workaround you can plug a float texture node into the texture power input. In this float texture node you can set values beyond 1.0 and with this setup it should work.

Yup, that works.
However, as I said in previous post. Pointless as the hard shadow screws it all up. No point even trying to use it.

Can you send to me this object? ... I want to be sure that this problem is also there in standalone loading it as OBJ file, to be sure that I don't have a bug in mesh code of the plugin.
I see this issue before in Standalone, so I think that this is a Octane problem, but I want to be sure.

Oh, it's definitely an Octane problem.
Object and Normal map attached. There was no UV. Just used the UVmap tool thingy.
It happens with bumps and normals.

OK, we investigated this and there is a defect in the Octane plugin interface, which limits the normal strength to 1.0. We will release a fix soon.
