Rock Pile Tutorial: MASH instancing

[@Adrian-tt3ev]

You need to turn off screen space adaptive subdivisions in order to make the instances work properly, the reason is this: since adaptive is screen based and all your objects are instances in different locations in world space and camera space the render engine does not know how to subdivide them, so you end up just with the auto bump mapping. Just disable screen space adaptive, set the edge length to 0 and increase the subdivisions to whatever you need them to be. This way it will work with the instances.

Thanks a lot for this info! Much appreciated!

[@ChrisHardcastle]

Loved seeing this. Thanks for sharing Tom.

[@tomnewburycg]

Hey Chris! Thanks to you and your team for helping answer some of my questions!

[@younisatwi3691]

Hey tom are you planning to make a tutorial on grass it looks fantastic

[@josephbradley1781]

Great video. Thanks for making it. It helps me a lot. I know this is 2018 but I was hoping you could answer a question. I made a scene similar to yours but I want to keep it an instance. However, when I export the mash instance and then reimport it to test, the three items and the plane are there but none of the instances came back. So, how do you export and instance so it will come back? and, will I be able to import it into another 3D editor like Daz3D or Max or C4D? Thank you for your help.

Amazing Tutorial, thanks a lot

[@tomnewburycg]

Thanks! Glad you like it!

[@peterallen8010]

Niiice Tom as always. Thanks You still use Octane? Or have you switched to Redshift?

[@tomnewburycg]

Hey Peter, I have never used Octane before, I usually use Arnold, but I am dabbling with Redshift in my personal work. It's pretty damn good so far.

[@julienlecocq9545]

Great tutorial, and great tool ! Thx a lot Tom. Maybe you have mentioned it and I didn't pick it up, but is there a way to avoid collision between scattered objects ? Might be useful in some cases. Merci :)

[@tomnewburycg]

Unfortunately I don't know a way of avoiding collisions in this circumstance. Bu I think it still works well enough.

[@julienlecocq9545]

Thx Tom

[@AlexStrook]

I used to this in max by dropping the high poly rocks using physics (Mass FX) and baking everything

[@SintyPone]

So good tutorial! Thank you 🙏🏻

[@TheParadigmShiftTV]

Did you use MASH for the grass? How was it done? Thanks

[@TBPFA]

I tried this on maya 2018 but whenever I put the selected mesh on the input mesh section under distribute, it doesn’t scatter objects along the mesh. Any ideas?

[@CursedRat4u]

Pretty nice, i wish it was in 3ds max :) but still epic!

[@marko8095]

That's cool. Thank you.

[@CarlTollefsen]

such a good tutorial, but it says that the rock assets doesn't exist anymore :(

[@twelveatlasfilms1928]

Hey Tom, love your product. I downloaded this file for use in my short animated film. I replaced some of the rocks with my own assets. My question is what render system did you use? V-Ray, Arnold? For some reason, the shader network is missing a material and the rocks are showing up Green in my scene. Thank you!

[@tomnewburycg]

Hi Ken, I used redshift, sounds like you need to rebuild the shader in Arnold.

[@twelveatlasfilms1928]

Ah yes, I installed the Redshift demo on my mac but it seems there isn't a lot of support yet for apple. I rebuilt the shdr using Arnold. How do you recommend I attach the specular roughness for the displacement?

[@artbydabney]

Great video, super helpful thanks!

[@ronniebarnett240]

I have a problem, maybe you can help me with: Im referencing in my created mash network of rocks (its one scene) into a much larger scene. Everything references without an issue, except the actual instancer(my pile of rocks) Do you have any idea why it may not be showing? In case you're wondering, this scene can not afford the number of polygons a rock mesh would demand. Im using Maya 2017, update 2(or 3, the latest one). I'm aware Maya 2017 is garbage compared to previous versions, but we really need the time editor for our purposes. So we're kind of stuck.

[@tomnewburycg]

Hmm, not sure on that one without trying it myself. Maybe try and ask this guy, he is always very helpful to me when I am stuck with MASH related questions. kzbin.info/www/bejne/fau7hpagr5KAaqc

[@syntaxed2]

Was FULL global illumination turned on when rendering at 21:40? What im asking is...you havent turned down bounces to force direct lighting only, have you? Render is so fast its almost unbelievable its full GI pathtracing.

[@tomnewburycg]

This is set to red shift's default settings, and by default GI is turned off. So This is just being lit by my area lights and the dome light.

[@syntaxed2]

Ahh ok, good to know! Thanks :D

[@oliverpayne1701]

im having trouble finding the mash option in my menus, do you know weather they have moved it in a recent update or is there a plug-in i have to activate?

[@tomnewburycg]

What version of Maya are you running?

[@oliverpayne1701]

it says on the 'about maya' section that its maya 2016 SP6, which is the most updated version, have i got to completely re download maya to get the 'ext 2'. it also a student version btw i dont think that should make a difference but yeah any help would be much appreciated.

[@oliverpayne1701]

fixed my problem literally 2 seconds after replying to your comment aha thanks anyway awesome tutorial

[@tomnewburycg]

Glad you worked it out! Happy learning!

[@oliverpayne1701]

would you be able to hook me up with a link explaining how i would go about exporting this as an obj or an FBX as idealy i would like to take the model into Substance Painter for texturing and im very new to using MASH

[@younisatwi3691]

Hey Tom I'm trying to purchase the scene file in Gumroad but for some reason it says its not available in my location, Any idea on how to get

[@tomnewburycg]

Younis Atwi I just heard about this today. You will have to use a VPN to change your IP address, just set it to a different country and then you should be able to get it.

[@younisatwi3691]

Tom Newbury hey tom it worked out i downloaded it , i do have a question to ask , where exactly do i place the hdri image , I’m kinda new to maya and i can’t seem to find a sky dome to place the hdri

[@indianeinstein1978]

nice video thanks very much

[@Slouworker]

Is there a similar tool for MAX?

[@mayurhedau5930]

Under Compound Object use scatter
