It seems that this is too difficult for me at this stage.. Maybe you will be able to show this process on the screenshot?EvolverInteractive wrote:The solution has already been given, in that some DDC for the green channel.
1. Get both Unreal and Octane going the same direction (even wrong)
2. Add to the normal node, a float value and a flatten normal
3. Adjust value positive or negative for best results.

I might have a fix. Would you be able to share some of the models you are using?amadudkin wrote:No, I initially checked the directions of all the normals of my object, they are OK, upside down doors-this is my UV mapping error. In addition to this, I checked other materials like concrete or wood textures, they behave in a similar wayChrisHekman wrote:I found the Quixel material you are using.
Seeing as the material is upside-down, am I correct in that you are scaling the model with a negative scale?
Do you have the same normal shading error when you are using the unreal sphere primitive?

Here is my model, on which I tested the materials https://drive.google.com/open?id=1isR7m ... bia76Hmn4h
Yes, the standart unreal sphere primitive has the same problem

Strange I am getting correct results on my end. Which plugin version are you using?

Could you try the latest version? I made a couple of changes related to normals in 0.25 or 0.26 i believe.amadudkin wrote:i use Unreal Engine 4.23.1 and Octane Prime 0_24_UE4_23 (the full name of my octane installer)

ue4 needs the green channel to be flipped .. octane need the green channel to stay unflipped. that is the case.
