Multi Map Exporter exporting multiple Displacement Maps

I have my model in Zbrush with 9 different subtools all sharing the same UV’s that I created previously in Maya. I am trying to create a displacement map for this model however whenever I use the multi map exporter and select ‘subtools’ and ‘merge maps’ it creates 7 different displacement maps instead of 1 map with all the subtools on it.

I make sure I only have ‘Displacement Map’ selected and nothing else yet when I click create maps a message pops up saying ‘Vector and standard displacement maps cannot be merged for exr format’, I click proceed and it takes me through to naming the maps and then goes ahead and creates 7 displacement maps. I don’t know why it pops up saying about the vector maps because I haven’t selected to create a vector map.

I successfully created a texture map from polypaint which merges all the subtools onto one map so I have not got a clue why it won’t merge the subtools for the displacement map. I cannot find anything on line regarding this issue.

What format are you using for the Displacement maps? Have you got the exr switch on in the Export Options> Displacement Map settings?

Here are the settings I have selected when I use the Multi Map Exporter and the message I receive afterwards -

Yes, you have “exr” turned on in the Displacement Map options. You can’t export as EXR format and have the maps merged. Turn off that little button and you will be able to merge your maps. 32bit Displacement maps will be TIF format.

Ah such a simple error but was causing me hell haha. Thank you so much for your help!

Just an update, I tried unticking Exr and it still didn’t merge my maps as a TIF? The message didn’t pop up which is good but its still producing 7 different displacement maps?

I’d have to see the model to see what the problem might be. If you can share it, let me know in a Private Message.

Praise be to Zbrush2019, I loaded my model in - followed your advice and it has created 1 displacement map combining all subtools. Thanks very much for your help!

That’s great! :+1:
