I have a sbs project file that I am working on for a client that has now become so large that I cannot work with it anymore. Loading the file takes up to 20 minutes and every time I try to do anything SD hangs for minutes at a time. My solution was to try and split the file up, however this is proving to be equally difficult. Have you got any suggestions re performance with larger files or ways to separate mdl from an sbs package into their own sbs package?
I've attached a log file if needed.

I have a sbs file that throws an 'unspecified error' when I try to export it. The relevant part of the log file is attached. Any help would be great.

I just have a question about exposed parameters in exported mdl materials. I noticed that parameters that I expose in mdl networks where the root node is a custom mdl package (which has exposed parameters itself) that none of the parameters are exposed when I export the mdl package. Is it not possible to construct mdl in this way and still have exposed parameters in the exported mdl?

Hopefully there is a way to do this already, however it would be really great if there was a way to batch export MDL materials from multiple packages. At the moment working on a large qty of mdl materials and using SD as the main editing tool is very time consuming due to the fact that we have to individually export every mdl. I would rather match a batch of edits in SD and then run a batch export to mdl while i am AFK.

I'm running into some issues with textures exported from Substance designer in MDL packages. I'm finding when I export the mdl package that the gamma value is being set to 'default' for all of the linear textures (roughness, specular and normals). This is despite them being connected through float nodes with the gamma values explicitly set to 'linear'.

In substance designer the textures are all rendered correctly as linear textures, however, when I render these materials outside of substance designer the default value used is srgb.
Is there a way I can force the textures to export as gamma_linear? Otherwise I need to edit the .mdl manually to change the gamma_default to gamma_linear.


I'm sure there is probably a simple answer to this but I haven't found one yet.
Is there a way to save the 3dview settings so I don't have to re-assign my materials every time I open a project? I am working on architectural materials and I have an interior test scene that I need to use to evaluate the materials, however it is quite tiresome having to re-assign the materials every time I load the project/package.

I'm having some problems with exported mdl's that use a substance that contains the tile_generator_color with 'input_image'  set as the pattern type.
The output in the substance render view looks fine, but when i export the mdl preset and use it in other applications the diffuse colour is all wrong. It almost looks like a gamma problem, but I'm not so sure.


I'm just new to substance designer and I want to procedurally create a tile pattern from a set of 6 images (each one of a single tile). Is this possible with substance designer, and where would I start with this?
The materials I am creating are also real world products, so I need to be able to specify accurate tile sizes (or at least get accurate width and height proportions).

Thanks in advance.
