Dilation fails in "Transfer Texture from Mesh" baker

Hello,

I'm reporting a critical bug in the "Transfer Texture from Mesh" baker introduced in Substance Designer 15.0.0 and still present in 15.0.1.

 

The Issue:
The Dilation Width (or Diffusion) setting no longer functions correctly. When baking textures (specifically normal maps) using this baker, instead of the pixels being properly dilated at the UV island edges, **black gaps and lines appear**.

 

Steps to Reproduce:
1. Use the "Transfer Texture from Mesh" baker to transfer a normal map from a source model to a target model.
2. Set any value for the "Dilation Width".
3. Bake the texture.

 

Expected Result:
The pixels at the edges of the UV shells should be extended outwards, creating a clean bake without seams, as it worked in all previous versions.

 

Actual Result:
Black artifacts, lines, and gaps appear along the UV seams. I have confirmed this is not an alpha channel issue and have tested with various settings and multiple texture formats (PNG, TGA) — the bug persists.

This functionality is a core part of my workflow, and this bug forces me to downgrade to version 14 to continue my work. It's frustrating when new releases break essential, long-standing features that worked perfectly before.

 

I hope the development team can investigate this issue and release a fix soon.

Thank you.

    Indeed, because we haven't released an update since the report of the bug. That being said, it should be fixed in the coming release. I'll update this thread as soon as the bug is fixed.

    Been almost a month and this issue still exist. Keep having to roll back to 14.1.2 for when I want to bake textures.

    Your answer is very good. But let's see how you fix the problem and develop the program. You need to prove it not with words, but with deeds.

      Thanks for the info. The workaround isn't a viable option, as disabling anti-aliasing produces poor, jagged quality. I hope a proper fix will be released soon.

      Hello again @SerQQ,


      Thank you for your swift reply and neat resources! I was able to reproduce the issue and identify it, as well as provide more details for this specific bug thanks to your case, so you've been a great help. The developers have been notified.

       

      In the meantime and just to let you know, I can tell you that this issue is caused by using Diffusion and Anti aliasing at the same time on specific normal bakers : Normal, Bent normal and Texture transfer with a normal map as a source texture.

      So for now, a workaround would be to either disable Diffusion or set the Anti aliasing to None.

       

      Best regards,

       

      Elio

        Hi @XimiK,

         

        Thank you for the message.

         

        You're definitely not the first one to dislike Adobe and I understand the frustration. But to be fair, this bug is only occuring since 15.0 (so only one week ago) and @Elio Meyer has answered (and acknowledged) the message 3 hours after it has been reported. Thank you @SerQQ by the way.

         

        I feel like your response to the initial thread is a bit off-topic, but I think it highlights a real frustration with the current Designer. I'd be very interested to collect your feedbacks and what feature you think is out of touch. Feel free to create a new post on the forum or to DM me if you want to continue this conversation.

         

        Best regards,

          Hello Elio,

          Thank you for the prompt reply and for investigating the issue.

          Of course. I have prepared a simple project that clearly demonstrates the problem. It contains only the two models and the PNG texture used for the transfer bake.

           

          You can find the project files at this Google Drive link: https://drive.google.com/file/d/1fzRNp-DMU0RFy_SDXnlKvbp3GrakBXq6/view?usp=sharing

           

          To reproduce the bug, simply open the project, select the graph named "gltf_version", right-click on it, and choose "Bake Model Information...". All the baker settings are already configured, and you will see the issue clearly.

           

          As requested, here are my system specifications:

          • GPU: NVIDIA GeForce RTX 4090 (Studio Driver v577.00, also tested on v576.52)

          • CPU: Intel Core i9-13900KF

          • RAM: 64 GB DDR5

          • OS: Windows 11 24H2 (OS Build 26100.4652)

           

          Please let me know if you or the development team need any more information. Thank you again for your help.

          Hello,

           

          Thank you for your feedback, I am sorry for the inconvenience. I have quickly investigated the issue and could reproduce similar results, although not exact.


          Could you provide me the assets you are using for this bake and your hardware specifications so we can further investigate the issue with the developer in charge of the bakers?

           

          Thank you!

            Completely agree! How long can this go on? It's obvious that damn Adobe is forcing the developers to work on some corporate nonsense instead of fixing and improving the core tools. They can't even add new features without breaking the ones that have worked perfectly for YEARS. The 'Adobe effect' is ruining a great tool. They are completely out of touch with the actual user base.
