Clone tool doesn't work for normal map

I want to use the clone tool to delete seams. I set it up to do that for the diffuse and the normal map. For the diffuse it works, but for some reason the normal map is keeping the seam. I attached a video.

 

I am probably missing something pretty easy here. Any ideas?

Correct answer Cyril Dellenbach

Alright, i was just a bit confused, that even in the viewport the "seam" was visible. If i flip the green channel it is better indeed. Sorry. 😉


Until now i didn't realize that the "seam" is just the inverted normal end of a rotated UV shell. So basically the thing you try to make me understand the whole time... 😄 Thank you for your patience.


No problems, it's perfectly understandable. I am glad the issue is solved and have fun with 3D!

 

Best regards,

Hello @reiniw10960852,

 

Thanks for the video. 

 

When you want to paint over a baked normal map, there is a specific workflow to follow with Substance 3D Painter.

 

First, under your Texture Set Settings, turn the Normal Mixing parameter to Replace.

Then, add a Fill Layer and link your Normal map to the "normal" slot. In addition, switch the blending mode to "Normal".

 

For the rest, it's as you already did, just turn the clone tool layer blending mode to Pthr.

 

Quick tip: You can right click on your blending mode to apply the current mode to all the channels.

 

Have a nice day.

Hello Cyril, thank you for your answer. I tried it with the workflow you mentioned, but it still doesn't work. I attached a video. Thank you for the quick tip. 🙂

I've made some tests, and did the same thing you did in the last video. I've placed the textures in a Fill Layer with the blending mode set to Normal and used a clone tool on a new layer set to Pthr.

On my side, I don't see any tiling issue. As you can see on this gif, the Normal and the Base Color are correctly hiding the seams in my material preview, even if the Normal doesn't look seamless in my normal view.

 

 

I even tried to make a quick rendering to make sure there wasn't any issue on this side, and except for my bad application of the clone tool, I don't see any seams.

 

 

Could you share with me a picture of your rendering, so I can see how the seams are reacting and adapt my tests ?

 

Best regards,


I need to export the diffuse and the normal map for my external renderer. It is nice that the quick rendering in Painter looks correct, but the exported normal map will still have the seam. And so will my external rendering. 😕😕
