Substance to Maya Displacement Map Issue (Bloating)

CanberkYucekok

Hi everyone, pleaseee help me i looked everywhere, it is 3:35 am in here my eyes are bleeding....

Anyways enough with my problems,

I am trying to get a render in maya, i exported my substance painter maps successfully, i load everything one by one and every thing goes great, yet when i try to plug height map, everything goes nuts in the render view, i repeated each step one by one just to get it right like 10 times already, tried different things bu nothing seems to work, i am wondering if there may be a problem with my software.

has anyone had this problem before?


THIS......






Becomes this...




thanks anyone.

Are u using Arnold? It seems to me that the max height values are pretty high, so your model appears to be "fluffy", cause the volume is not just misplaced as it is "swollen" and even hitting the bounding box.

Thank you @Yerus you are very kind to answer,

Yes I am using Arnold. This is the shape node setting that i am using, one might say this is default.



When i tries to connect a file note to displacement mat, it does not seem connected in the hypershade, i am not sure if this is what supposed to be.



I am trying to tweak some setting but nothing seems to work, it even starts not to update in the render view when i try.

Is there any other setting i should try?


Thanks.

woooo

LOL, I'm no expert in Arnold, have u tried putting the normal map in the 'Attr Ed. > Geometry > Bump' and play with the values of the bump depth and color balance?

oglu

have you tried the new plugin?

@oglu as far as i know it works only with substance designer, is there a substance painter workflow for that plugin?

oglu

i see. could you upload a test file.
i will take a look.

To get displacement working you need to connect the dispmap into the disp input of the shading node.

could you post some maya wireframe shots?

@oglu thank you thank you thank you for your interest, i upload one piece of the mesh since the whose scene may be too heavy to upload, this particular mesh looks like this when i render with the scene settings.



this is the substance painter viewport look:




If you can take a look it would mean a lot since i dont have another computer to double check the scene.

Have a nice day.

I wont use displacement at all in your case. The texture you are using i just one flat color with some letters. Arnold is exactly doing what this texture tells it.

I recommend to combine this heightmap into your normalmap.

Set the scalar zero to 0.5, I bet that helps

Painter displacement  is a signed float with a range of -1 to 1

It looks like your renderer is expecting a range of 0-1

In order to conlude this topic,

I did what @oglu said and did not even bother to add height map and it work pretty well, as i was exporting from substance i used NormalGL and it seems to combine normal information with height information. So when i rendered in Maya Arnold it was very close to substance.

I tried to change values of different parameters but i could not manage to come up with a good result.

Here is there arnold render with no height map.

And i also added HDRI.

Make sure you're model has UVs
