How to Make Realistic Grass with XGEN & HDRI using Arnold in MAYA - CGFamily

[@wedditorspostproduction7840]

Fantastic video i learn so many things in that video you're just awesome man 😍👌

[@CGFamilyStudio]

You saying that has made it all worth the time! ❤ We thank you for those kind words & time. See you soon again.

[@SilesianWarrior]

If your grass is not visible in Arnold, go to your xgen description like in the vid, go to Preview/Output tab and in output settings select Arnold Renderer. Scroll a bit further down and in Arnold settings click "Apply Hair Shader". Save entire maya project, close, open again.

[@fallencookie2051]

Thank you. Altough this seems to work with cpu rendering only.

[@hydr4128]

I'm amazed by seeing the render speed

[@CGFamilyStudio]

haha, Just the video in fast forward, to save time.

[@smashedlegends]

Hi! Why you did not choose the option that XGen has for grass? (when you clicked on description).. Thanks!

[@MissingTexture]

can the grass be exported as an FBX?

[@accuset]

This was so necessary, thank you!!!!

[@RoanRossey]

Nice video man! well explained.

[@CGFamilyStudio]

Thanks, Glad you liked it! ✔

[@trystanbleuven791]

such a great video! only is that in find my shading not really realistic like the grass as too much roughness, and there is no parameter for it, any solution ?

[@borisboidron9116]

Great ! Thank you :)

[@whippet_boy8594]

This is amazing! really good English too

Thanks a lot!

Any time ✔❤

I can't open the expression editor option. How can solve this?

[@pankiberry9493]

same problem 😕

[@CGFamilyStudio]

Hey, when you create a new Description in Xgen. Make sure u select Expressions not spline or anything else. Then it should work unless there's a bug somehow.

[@albiayubi_4178]

My object is dissapear when i try to render arnold.. i just see the hdri but not my object.. any solution?

[@Mr.Bumhaniya]

For some reason my grass is rendering white even after applying Green colors as you did. Any idea why?

[@baibhabbhuyan5196]

Great video, i have a issue, when i rendered it turns into flat cards instead of splines. Why is that?

[@ZibidiZuker]

You made a mistake there. You are using 2 HDRI unknowingly. If you added an aiSKydome then go to the attribute down to the visibility, put the value for the camera to 1. The way right now the skydome is giving you light and you get the same light from the render settingsmenu which will cause you the noise.

How do you animate the grass?

[@TerroR007]

Now do you know how to animate them?

[@marksantiago22]

useful this kind of tip gonna save

[@CGFamilyStudio]

Glad to hear that!

[@marksantiago22]

@@CGFamilyStudio please make night sky just like anime in japan that kind though please theres no kind of tutorial on that in maya only in blender.

Hello, how to solve the white grass. it doenst show it green

[@CGFamilyStudio]

Hi, Try saving your Project and re open. Maybe that will help.

[@sarbendrabohara7995]

i saw full vedio but you know grass will not semelar in all aria some where tall somewhere short so my question is how to creat tall and short grass with same aria ?

[@CGFamilyStudio]

Hi, your Question is not so clear to me but let me try. If you mean that you want to keep the grass same & don't want variation in length then simply don't put any expression in it & use the slider. (in this case, you might also want to keep your ground flat) If you want a certain pattern or length gradient then try some 'sample expressions' do this - .click on little down arrow which is on right side of the slider - go to load expression - samples, now try different samples & choose the one you want. (you can also edit these in editor) you can also click 'Create Map' and then paint your weights for length. I hope this is what you were asking, feel free to ask if you face any further issue.

[@Jertva21goVeka]

help me please ! Do everything as in the video, but the grass is not displayed on the render.

[@CGFamilyStudio]

Hi, I would suggest you to make a new project and start fresh from there. sometimes if you miss something and try to correct it again and again it creates issues. If you encounter the same problem again, mention your Maya version and if you face some error on script editor when rendering.

[@Jertva21goVeka]

@@CGFamilyStudio I solved the problem, I just had to save the project.

[@CGFamilyStudio]

Wonderful, glad to hear that. 👏

[@igotmello]

Thanks!

[@CGFamilyStudio]

Welcome! 👌

[@Mynkkk1717]

In my case grass is not visible??

[@williambasile3594]

I have some difficulty with Arnold render, it's not showing the grass... how can I fix it please .

[@CGFamilyStudio]

Hello William, 1 of our viewer also had this issue. That was solved by saving the Project & then Rendering! Hope that helps you too ✨

[@TerroR007]

How to animate it?

[@tildo2001]

Hi, since created my grass is totally white even in the render :c you know what can be? textures and materials are enabled :was the lighting of my scene, is a little bit dark and colors are not showed for some reason :/

[@CGFamilyStudio]

Glad you found out the issue. I also face many random errors when using Xgen. That's why i like to save my scene after every little progress. 😂

[@ВикторияАндрейченко-о7ь]

// Error: line 1: Cannot find procedure "XgCreateDescriptionEditor". how can i fix it problem to continue to make grass? i can not create description(

[@CGFamilyStudio]

Hi, i feel the issue is regarding a corrupt setting in xgen. Do you see some error when you open the maya also? in any case i think it will solve if you reset your maya settings. Do this - - go to your my documents folder -Locate Maya Folder and open it - choose the folder of the version you are having issues with - Delete the folder & then start Maya again. (you can also just delete the maya folder in documents if you don't have anything specific stored in there) hopefully it will solve the problem. :)

[@ВикторияАндрейченко-о7ь]

@@CGFamilyStudio i did it. and now i see error like problem with xgen mel

[@CGFamilyStudio]

Hello again, i did a little 🕵️‍♂️ research around the internet and found this article on Autodesk forums. forums.autodesk.com/t5/maya-modeling/xgen-error/td-p/5715576 What it means for you is that, if your issue turns out to be the same - it might be due to the name you have set for your PC user. i suggest going through it. Tell me if it helps! 👍

[@ВикторияАндрейченко-о7ь]

I'm flattered thank you for your time and help I'll do it now, see if it works out thanks a lot!!!

[@ВикторияАндрейченко-о7ь]

I've changed my PC user name and the name of relative folder in C:\Users\. Now it works. Thanks a lot!

[@ВикторияАндрейченко-о7ь]

hi again)can you help me? i can not select object how to solve that?do you have idea?

[@CGFamilyStudio]

Hi, How are you. Hoping the issue is resolved! If not, revert back and we will see how we can help.

[@im_sandeep_kaskar]

Why am I not getting a Diffuse option in xgen_hair_physical1?

[@CGFamilyStudio]

Hi, can you elaborate your question? like what version of maya you are using & what are you trying to do specifically. - If what you are trying to do is assign a material on your xgen collection, simply go to outliner select the "Description" & right click then assign a new material. 👍

[@im_sandeep_kaskar]

@@CGFamilyStudio I have got it. Mental Ray was my default render engine that's why i didn't got diffuse option in Attribute editor. I have to change renderer to Arnold to get that option.

[@CGFamilyStudio]

Glad to hear that it's resolved! 👍

[@jacksonlamme]

my density is at 300 and its not that dense

[@CGFamilyStudio]

Xgen is tricky when you start to use it for the 1st time. The density can also be affected by the scale of your model. If the model is bigger/scaled UP or your metrics are in meter, then you have to pump those values in xgen Up too! Hope that helps. 👍

[@dubtube6691]

It's a joke for 2020

[@CGFamilyStudio]

I wonder why

[@dubtube6691]

Horrible maya
