Hello! I've searched the forum and re-read the manual a bunch of times before posting this question. I'm having a lot of trouble getting a material i'm creating to displace correctly. I'm getting the dreaded "spikey" surface and cannot seem to get this to turn out how I want. My usual workflow is modeling in sketchup and then rendering from there, but now i'm using studio and importing the "basic" geometry shapes in hopes of getting it to displace correctly with no such luck. Can anyone run this as a displacement on a basic MXM and see if it works for them?
Thanks!

It works fine -- set precision to adaptive... and wait

were you able to get it to work in an actual rendered output? What settings did you use besides having adaptive on? Done in Studio or what? My preview images look perfect but the output renderings spikey.

[Half Life]

screen cap of your output would be helpful...

Best,

In studio with the 8x8 primitive plane works very nicely at precision 64... less subdivision means higher precision needed -- but everything looks normal here.

That one is with settings of height 2%, offset 0, adaptive, no smoothing.

edit: this one has a surface wood texture, same disp map though

[Half Life]

Smoothing isn't something that you usually need to turn off and it certainly isn't the culprit here... it looks like a precision issue for sure -- this may be a long shot, but do you have more than 1 displacement in the material... it could be that a displacement with the wrong settings is being used.

Also worth trying this material on the primitive 8x8 plane to see if you get better results.

Best,
Jason.

Alright with the settings of precision 64 instead of adaptive it's working on the 8x8 plane, let me try it in my sketchup model.
Nope, not working in the sketchup model, i'm still getting spikes although they are more defined and spikey-er. So it looks like it may be a sketchup plugin or sketchup geometry problem? Hmmmm

[Half Life]

Could be a scale issue --is the model very small or very big?

Something I just realized, the geometry isn't an instance is it? Instances don't support displacement (although I'd assume that means nothing at all versus what you are getting)

Best,
Jason.

filter map off ? or on?

[3dforall]

The plane i drew here in sketchup is an 8x8m plane, i imported the material that was working in Studio into sketchup and directly applied it, the scale seems TINY in sketchup as opposed to studio which is odd. Here's a screen shot of the sketchup setup and the render result. I'm not sure what filter map means.

I dont THINK im using instances....

A displacement map can be out of scale.
In studio select the material you have problems with,
in material settings click on "set texture displayed in viewports" and select the displacement map.
Now check the viewport if it's not out of scale.

[Half Life]

8x8 means number of subdivisions not size -- size is 2 meters for the primitive... so the precision would have to go wayyyyy up for that plane from Sketchup.

Filter is what "interpolation" used to be called -- he's stuck on 1.7... I tested with both on an off and on is fine to soften hard edges a bit, but not to the extreme you are having.

Best,
Jason.

Jason are you trying this from Sketchup? It may be an issue inside of that plugin. I'm trying all different scales and precisions with no luck

[Half Life]

The issue with textures from Sketchup to Maxwell is a complex one -- but the bottom line is if you edit your texture in Sketchup (the actual Sketchup material) to be the size you want it to be and leave the scale to 1x1 relative in the Maxwell material then you will get a 1 to 1 WYSIWYG approach.

Also don't use pack and go (in the plugin export prefs) unless you need to, as it can cause a bit of texture map confusion sometimes... again, too much to explain here.

Best,
Jason.
