Shader Mixer "Granite" brick doesn't create displacement anymore

Posts: 17
Hi all,
Those last days, I try to re-use a shader I made few months ago (ok ok ok ! Years !). It's based on the funny "Granite" bick. But no displacement created at all.
So, I create the simplest shader possible with displacement, I mean : "DS Default Mat" connected on root "Surface" and "DS default Disp" connected on root "Displacement". Then I connect a "Granite" Brick on the "Displace" input of the "DS Default Disp". No displacement at all.
I tried to "Multiply" by 2 the output of "Granite" with a brick "Binary Operation" then I normalized the output between 0 and 1 with a "Clamp or Step" brick setted in "Smooth Step" to have a high contrast. No displacement.
Believe me, I made all the tests possible on options of all bricks, etc, but nothing better.
All other bricks (Checker, Clouds, Fractal Sum, Marble, Noise, Spot, Voronoi, ...) are working fine.
I waaaaant my Graniiiiiiiiiiiiiiiiiiiiiite baaaaack ! Pleaaaaaaaaaaaaaaaaaaaaaaase !
Dear friends, I woulld like to know if it happens on other systems than mine, or if it's just MY granite brick who want to make me crazy ?
Thanks to all

As far as I can see you have connected only the N (normal) output to the Displacement root - that is for normal/bump mapping, it won't do anything to displace the mesh. For displacement you need to connect the P (point) output to the input on the root as well.
Thank you Richard but N alone (Bump) or N AND P (Displacement) connected, the result is the same. No 3-dimentionnal effect at all (to prevent to use the word "Displacement").
Thanks for your help.
I have plugged in both n and p but I'm not getting displacement...I can get the granite texture to show in the diffuse though. Do we need to do a bug report?
I'm pretty sure I've remembered how to do displacement but here's the network. Notice the preview above the displacement standard. Edit I did also try plugging the granite into both displace and strength individually also.
Exactly Pendraia. I forgot to notice that in my first post but you're right, it's working fine connected on "DS Default Mat" but not on "DS default Disp". Thank you.
My pleasure...it's frustrating when things don't work as you expect them to. Knowing that it's not just something happening to you can help ease that a little but we may need to file a bug report. Hopefully Richard will see this and comment...I'm not sure how we file bug reports now.
I just did, Pendria. Thanks again.
To send a bug report, you choose the "Help" menu in the DAZ shop page then "Help Center" to access the Knowledge Base and you will find the option "Submit a Bug Report" at the top right.

Applying the Granite to both the Displacement and Strength channels mutes the effect - essentially you are turning it down as it gets into the negative values, so only the positive shows. However, with the min and max turned up for exaggeration I do see an effect both there and with only Displace connected.
Thank you again, Richard:
1/ I didn’t see Pendria connected both but I didn’t, and it’s not working. Miss Pendria ? Is it working for you with strength disconned ?
2/ The shader setting of Richerd's picture is exactly the one not working for me, displacement connected or not. Totally “bald” aspect (see pic Ex1s).
3a/ BUT, with N & P connected, if I turn up the min (-5) and max (+5) for exaggeration (as you wrote) something strange happens: A kind of pick is growing in the previews and the sphere render shows its wireframe (see pic Ex2s). The sphere is smaller than for -1 & +1 which means displacement is working negative (see Ex3s). I tried -10 and +10, sphere is smaller, the pick in the upper part of preview is higher and a pick appears in the lower part of preview (?!).
3b/ With the same settings (-5 & +5), but with P disconnected, nothing strange, no pick in the previews, but the render shows also the wireframe (see pic Ex4s). The sphere is a bit BIGGER than for -1 & +1 (see pic Ex5s)! ((Please dont ask me if I moved the camera ! :-))
Thanks very much to try to help me. It was not a joke, I really like to use Graphite.
Best regards
I guess the peak is trying to preview displacement with hardly any area displaced. Is this the current versions of DS- 4.7.0.12? And is the sphere from Create>New primitive? I assume there's normally only one sphere present in the scene.
Hi Richard, I did mention I tried both displace and strength individually as well as trying both together. I didn't fiddle with the default settings though I would have expected to see some change though. Didn't know that using both would mute the effect though so thanks for the info.
However, why is the preview showing red and green in the displacement brick?
My sphere was created that way and the only one in the scene from memory it had 48 segments. So It should have had sufficient geometry. sorry I'm not on the computer and I didn't save the scene.
Hello again.
1/ Is this the current versions of DS- 4.7.0.12?
Yes DS 4.7.0.12 Pro Edition (64-bit)
2/ Is the sphere from Create>New primitive?
Yes. Sphere: 1 meter 32 segments 32 sides.
3/ I assume there’s normally only one sphere present in the scene.
No. An horizontal plane was there as ground. I forgot to delete it before the tests. This plane is coming also from Create>New primitive: plane 20 meters 32 divisions. I just deleted it to redo the tests and,obviously, nothing changed.
I'm also using this version...same network as yours Richard
Still no displacement.
Thought I'd try a different texture with the same network. This time I used the checker default settings on the brick and the displacement works. So there is a problem when combining displacement with the granite brick despite the granite working in the diffuse.
I just tried again, using the same sphere settings and leaving all of the bricks in their default states, and I still get displacement. I can see that Pendraia, at least, is a Windows user like me so it isn't a platform-specific issue. I suppose it may be worth your posting your render settings.
Mine were fairly standard Richard...
Horizontal
Bucket Size 16
Shading Rate .50
I haven't really messed much with render settings recently...been too busy.
What version are you using? 4.7?
4.7.0.12, the same as you. My Shading Rate is also .5, which is, or should be, the only value you mention that would matter. This is very odd - I wonder if it could be some kind of plug-in interaction? That's definitely clutching at straws.
Not sure...could it be something else that's on the system that is interfering with how it operates?
I also have problems with the weightmapping brush crashing...haven't followed it up yet due to lack of time. Other than that I don't have any issues with DS at the moment.
Yes Pendraia, I did the same, and all others are working fine (Checker, Clouds, Fractal Sum, Marble, Noise, Spot, Voronoi, ...).
Following the request of the help center, I sent them this early morning (for me) the granite block saved, my test shader saved, a print screen of the shader with the little peaks on the previews and the renders.
Hello all,
I just got the answer from the DAZ Help Center. They are lucky like Richard. They dont have the problem even using my granite block saved and sent to them.
Thanks again and happy shadering ! :-)
Bad news, Miss Pendraia, the only conclusion we had, with the help center, is that I have to re-install DAZ Studio.
Thanks again and again.
No problem...wish we could have found a solution.
Hello!
DAZ Studio uninstalled (with folders and registry cleaning) then reinstalled.
Same problem with Granite Brick.

Hi ! Long time no see ! :-)
With the new STUDIO IRRRRRRAAAAAAADIUM, "Granite" brick still NOT creating displacement. Thats all ...
Regards to all.
