Changing MDL version

Hi everyone,

 

I'm working on a proof of concept with MDL graphs. Currently, substance exports MDL graphs in MDL version 1.5. Vray only supports MDL version 1.4.3. 
Is there a way to set substance MDL graphs to an older version? As to not have compatibility issues. 

Thanks

Hello @jens_ha,

 

As the MDL version is linked to the Iray SDK, this cannot be changed in Designer. I will bring up the topic of compatibility options with the team, although we would need to check if that is supported by the SDK in the first place.

 

The most recent version of Designer which uses version 1.4.x of the MDL specification is 9.1.3 (2019.1.3, build 2520).

 

Best regards.

Hello,

 

The MDL version present in Designer is defined by the version of the Iray SDK, as that kit includes both the MDL and Iray librairies.

As such, it is not possible to change the MDL version, and there are no compatibility options available on export. Thank you for your patience regarding this limitation.

 

Best regards.

    Hi luca,

     

    Could i change the SDK used in substance?

    If not, is compatibility options something for the future?

     

    And which version of substance still uses the MDL 1.4.3 version of the SDK?

     

    Thanks
