It seems your Materia filter has some problems. Reimporting it may solve the problem:

- Find the localization of the filter: (something like "C:\Program Files\Allegorithmic\Substance Alchemist\Resources\assets\Internal\materia.alchfilter")
- In Filter panel, click the + button and "Import Filter".
- Browse to materia.alchfilter

It should warn you about version downgrading.
Agree to this... and it will reinstall the filter.

If this does not work, please let me know.


Well, it seems Image to material has worked, since normal informations have been computed.
- Could you check in the channels settings "Base Color" has not been disabled ?
- What are the output maps displayed in the 2D view ?
- Could you try and export this material to jpeg and see what are the output ?


I am deeply sorry, but AI powered bitmap to material requires latest CUDA runtime from NVIDIA, and this version of CUDA is no longer compatible with Quadro K4000.

The only way to continue to use Materia with your GPU is to reinstall version 2.2.

For information you can access the list of supported GPU here:


Hello Ben,

Indeed, this should work.
Have you tried to update your graphics drivers?

If this does not solve the issue, can you send us a log file ?


Hello PSNick,

I am sorry but, for now, materials exported by Substance Alchemist are not parametric.


Hi MehrRettig,

Indeed, left clicking on a layer in the stack should toggle the properties pane just on the left of the stack. Can you see this pane and it is empty, or can't you see it at all ?

You are talking about filters... does this mean you manage to have this panel for materials ?
I don't really understand what you mean by twitching. Would be nice if you could send us a short video of this. Could you also join the log file ?
Thanks for reporting the issue.


Hi Tarek,

The AI Powered image to material is only available for NVIDIA GPUs, with more than 2GB VRAM.
Could you send me your log file so I can check what’s going on ?
(It is located in %appdata%\Allegorithmic\Substance Alchemist\log.txt)



Alchemist does not add spaces, unless your material name contains spaces. In the export popup, if you change the value in "Name" textfield to remove the spaces, you will have no spaces in the generated file names.
Furthermore, depending on your workflow, you could change the export preset (using Blender Cycle preset generates maps with no space in them)



For now, materials created in Alchemist cannot be tweaked once created.
You may modify your material by clicking on it instead of dragging in the stack. Then you could create a new version of it with the desired parameters before adding in a new stack.

Regarding your thumbnail issue, it may come from an issue with multiple monitors with diffirent resolution on MacOS. Could you please try to unplug your second monitor before generating a thumbnail ?


Hello Keith,

Could you tell me if you are using an export preset and in what format you are exporting your material ?
Are you using filters in your stack or does it happen on a very basic stack with a single material ?


Hello etie777,

For now, Alchemist exported material are no longer procedural, so this is a normal behaviour. You need to customize in Alchemist before exporting it.


Hello Peter

Is there a way to utilise the backup "appdata-folder" to get back the old Alchemist creations?

For the moment no. have you reported a bug for the crash you experience ? If your Alchemist database is not too big, maybe you could send it to me, so I'll have a look on what's wrong with it ?



I see.. I am just trying to find a material that I created in Alchemist, I could find Json files on my computer but I just can not see under my open project menu, it only shows some of my recent ones. That's the trouble..

Materials are not projects. A project is a list of collections, each collection containings multiple materials. When you open a project, materials are not displayed. If you are looking for a material, you can use the search bar on top of resources panel.


Hello pinarer,

Alchemist projects are not stored in dedicated files. They are only accessible from the file "open project" menu.
The list here contains all the projects you created using file "new project".

A project is a list of material collections, associated to a workflow. What are you trying to open ? A material ?


Created projects are stored in Alchemist Database. They all should appear in the list in "open project" window...

Could you please open another project and use search bar to find an asset you created in one of the missing projects (if you know its name)? It should be found, whatever the current project.
