How to create realistic grass edges using Forest Effects
HTML-код
- Опубликовано: 18 авг 2024
- In this tutorial we explain how to use the Tint By Boundary feature to colourise grass where it meets an edge. This is commonly seen in real life when there’s heavy footfall or the conditions mean that there’s less water available near the edges of a lawn because of the poorer quality of the substrate.

We need more of these effect tutorials. Funny thing is, Ive been using FP for a while now and never knew that much about the effects panel. I always thought it had to do with max's standard effects, like wind and such. So yeah please make more of these effects tutorials
sameee. Such a great video
Just what i was looking for years... Give shape to the grass is very important to give more realistic renderings and exclude more post-production editions.
Simply fantastic .. Thanks a world!
It is very nice. Thank you
nice one ! Thanks!!
Lovely!
Thanks
so great vedio ! Thank you soooooooo muuuuuch!
I'm using corona layered material instead and when i plug forest color into the blend/mask slot, iget dry grass at the edge and everything else turns white.
Please, if you know how to correct this, share it here. I would like to know too. Thank you!
same problem i use defaul blend but didn,t work and also the white and grey grass are not on edges but random on all surface ?
Hi I am suffering the same issue, did you find a solution?
The best way to Solve it is to add a Corona Layered Material to each slot in the multi-subobject material, in every case you connect the original material in the base , the other material , the one you want in the edges, in the layer one and in the mask the forest color. You have to repeat this in every slot.
At the transition in the 2:19, how can i get there? I mean, you are checking the override option of a Forest Color map, Is it the same map that you are using after at the VrayBlendMtl?
Thanks!!
Exactly my question as well..
It works fine, but I encountered a small problem: If I want to make taller grass around stones or a stump and I have a few more paths in the scene, the grass also grows along the paths. How to solve it?
How did you assign the trunk as an exclude boundary here? Sorry, very new.
from one minute to five seconds, making the grass layer less healthy, I have followed the correct procedure many times but the grass still does not change color, is there any way to solve it, I am using version 8.2.2
2:16 this part is extremely confusing. Which forest color map are we supposed to use to make this work? There are a dozen of them in the forest material.. I never got this to work.
The next section explains the material setup. In this case you don't modify an existing Forest Material, you use a new one as a mask in a V-Ray Blend material.
Can anyone get this to work with Max 2023, FP 8.2.4, Vray 6 Update 2? I've followed this video 15 times, step by step for the last few hours with no luck getting the effects Tint by Boundary to work.
Figured it out. What is completely glossed over in the video, and maybe the behavior has changed since this video was done, is when instancing the material from all the selected Forest Pack geometries (grasses), and you add the vray blend, forest color map, is after you are done, you have to not apply material to your FP object, but to drag the output of the Vray Blend Material back into the FP material slot on the right modify menu so all objects are updated with new material. It says it on the website tutorial, but doesn't mention that in the video.
When you use the forsst color as a mask and uncheck the override, does it mean you can use only one forest color in your material? So no color variation on the grass itself from forest color when using this technique? Thanks
You can still use colour variations by using override for the Forest Colour maps that affect the material colours (Usually in the diffuse input). The Effect will only affect the maps with Override disabled.
Hi how we can do this with corona?
wow,I Like that but it dosent work in vantage because vantage dont support vray blend,is that a way to edit material with foret map 1 by 1?
Although you could use the Forest Colour map as a mask for any map or material that accepts them, I'm not sure if Vantage would support this feature at all actually because it requires Forest Pack to control a Forest Colour Map. When exported to Vantage, the scatter is converted to regular instances.
The second effect you apply (Z scale by Exclude Boundary) doesnt work to me as in your video tut. Do I have to specify the trunk mesh in some way or add it to forestPack in some way? I'm using licensed Forest 7.4.3 and Vray 6 hotfix 2 versions, max 2022. Thank you.
Try adding it to the Areas list as an Object Exclude Area, then it should work 👍
@@itoosoft yes, now it works correctly. Thank you very much.
你能告诉我你正在演示的具体版本号吗？我的 8.0.6 不起作用？？
This doesn't work with V-ray GPU. Apparently there is a work-around - can you explain how to do it?
Unfortunately V-Ray GPU doesn't support this technique. As with most GPU renderers, the developers write a translation for our plugins to ensure that it works with their engine (we can't do it ourselves as they have no API). This can mean that not all features are available on the GPU.
@@itoosoft thanks for the reply! I managed to get a pretty similar effect using the grass edge technique.
@@thepabs3000 Ah - yes we should have thought of that. Glad you worked out a workaround.
Still cannot use sharp edging with octane.
Unfortunately that's an Octane limitation over which we have no control. Unlike V-Ray, Octane has no SDK we can access so we are dependent on them supporting Forest Pack rather than the other way around.
Doesn,t work with me the color apply on randoms not on edges .. and second thing where to find blend in corona render engine ?
This was recorded with V-Ray, but you could certainly do a similar thing with Corona. You can't use a blend material thought, instead you'd need to add CoronaMix maps or similar to the diffuse input of the individual materials rather than use a Corona Layer material. This is because Corona doesn't currently support using Mult-Sub materials inside a CoronaLayer material like V-Ray can.
@@itoosoft I used coronalayeredMTL
@@itoosoft everything works they didn't give me any error but the problem is the grass become white or yellow grey and didn't applied to edges
@@itoosoft u can,t add color mix to multi/sub material
@@barbarossalivegaming Drop us a message at helpdesk@itoosoft.com (preferably with the file) and we'll be happy to take a look.

No solution for Corona?

@@itoosoft thank you for replying! But that's just too much work. Would be nice to have an automatic way of doing it, like add a button on "optimize material " menu, just like we have to add forest edge on opacity slot.
@@BartVlogs Thanks for the suggestion. I'll pass it along to the development team. Cheers!
how to do it in corona????
You can use more or less the same technique, except Corona doesn't allow you to blend a multi-sub object map (unless that's changed) so you'd need to add Forest Color maps to mix the diffuse textures instead.
@@itoosoft thank you, will try now
