Issue: connecting the AIBump2d (or 3d) out value into the normal value of the bump map doesn't create cool breakup as demo'd. Solution: Make sure that you are plugged into the "normal camera" instead of the "normal" input of the AIAmbientOcclusion node. You can right click hold the node and select "show all attributes" to find it. Struggled with that one for a little while!

Hey, Arvid... so, i actually work with cutting gem stones, and a little thing i thought you might find interesting..... the rainbow sheen you see on those blue quartz is from gold..... the blue quartz is called aqua aura, and what it is is a process of spraying gold onto quartz and it fusing with the surface creating the coloring. they use all kinds of metals to get different color effects. but that specifically is what is causing the rainbow on the surface..... quartz does however cause prisms inside the stone itself the way it bends light. but the surface is a metal infusing process.

It is rare to find such a good quality high end CG channel. All your videos are relevant to my searches - subscribed, love it!

Thanks for State Vector tip! Ive been using a 3D ramp to get something similar but this looks like a better approach

It would eb so cool if you covered a dust tutorial. Like fine dust creation with curves for fine details, etc...

Is there anyone following with Houdini/Arnold? I cannot figure out bump. I'm not getting result when I plug bump vector to normal and of course there is not normal camera thing. if someone knows what to do, please share.

Hi Arvid! I love your tutorials and I was wondering if you’d do a tutorial on how to shade a dirty finger printed mirror, I looked around for hours but I couldn’t find anything helpful so I was wondering if you’d ever do one perhaps!

Hello, I don't see the ID slots in my AiSurfaceShader that you attached the ambient occlusion shader too, any idea why? Thanks

So im using Maya 2023 with MtoA 5.2.1.1 and when i try to connect the aiAmbientOcclusion to AiBump2d then to Normal Camera it doesn't give me a result. Has anyone else had this issue?

how do you get the Id 1,2 and so forth on your aiStandardSurface ? Beacse I'm following along to this tutorial but I don't know where to plug in my occlusion nodes now

First of all, thank you for this tutorial, it's really helping me a lot. I have a question, if do my crystal with a displacement map from zbrush (as i want it to be a part of a big scene and there's multiple crystals so i cant bring the high poly), when i setup the displacement in maya, the object get smoothed when switch the subdivision type to catclark in the arnold part of the shape node, so i lose all the hard edges and my crystal get all roundish. I don't know how to solve that issue at all. Any suggestion ?

i just started learn Maya and now i understand why that series is so important. 2 questions: 1) Could you show final product of particular tutorial during introduction - miniature is to small ? 2) There was any video tutorial about converting or change blender shader node into arnold shaders ?

A comentary that I have is about sculpt the crystal in Zbrush and export a displacement. I tried this way and the displacement give some problem, when you divide with smooth, the hard corners present some problem in the displacement, because in this map, appears a white areas that affect in the displacment when you applies and thar cornes are inflated in the render. Actually, the best solution is use a morph target al least, and re import the crystal obj, and use the morth brush to recover the deformation for sculpt n the lowest subdiv. if anyone discove a best way to get a clean displacement, please, tell me.

thanks so much for sharing your process!!

Where those ID tabs comes from?

Thanks for the video. its pretty good. Can u just say us when are you going to upload the second part please !!!

I am really excited about this tutorial. It looks like a great place to start for what I am trying to create. However maybe someone can help me. You start with the ai_crystal shader. I cannot find that. Where does that come from?

Thank you for the great tutorials. They have helped me a lot. I have a question but it's not directly related to Arnold. I am trying to create scene with lot of vegetation and I am planning to use paint effects. The vegetation will have a turbulent force to simulate wind. I plan to use MASH to populate the scene. My question is, is there a way to bake this paint effect animation to geometry, and possibly convert it to Arnold stand-ins and use in MASH? I tried just converting paint effects to polygon but then my scene gets too heavy for my PC to handle. Or is there a different way to approach this? I would really appreciate any help/ suggestion you can give.

YAY!!!!!!!!!!!!!

Hi Arvid, I make one with subtance painter i think its looks pretty cool but i want the opinion from a professional like you, so how i can show my work? This crystal rock that i made its actually the first 3d thing with a complete 3d workflow behind. Cheers

Great tutorial! Exactly what I was looking for I think. But... I get stuck at the beginning. When I plug the AO to ID1 it renders black. Looking at your scene graph I guess you have some kind of IBL going on. Could you point to the basic scene setup or drop a few lines about how you setup the scene? Thanks!

Hi Arvid! Why I don't have "aistatevector"？ maya 2018 sp1

thanks

I was trying this but i dont have the id atributtes in my aiStandarSirface, what should I do?

Hello Arvid, thank you for the tutorial. I have a question about the app, by any chance is It going to be available in the play store soon?

Thanks for this. Just updated my version of Arnold to 5.1 and for the ambient occlusion node I cant seem to get any feedback if I attach the noise parameter to the normal node, even after adding the bump 2d. Could this be a bug on my end?

Very good explained bro

Hi, great video as always! But I have a question, where I can find ALshaders? the website is down now.

Does most of this transfer to c4d for Arnold render
