Nico_be Posted December 10, 2019 Share Posted December 10, 2019 Hello, In some files, when I apply a grass texture on a polyline, the grass appears under the polyline. Not all grass texture because some of them are good. Sometimes, on my PC everything is ok and with the same file on vectorworks Cloud, it send me a pdf file with errors, see image bellow... On the image we see the "roots" of each grass. Is somebody have the same problem? Quote Link to comment
Guest Alex Sagatov Posted December 10, 2019 Share Posted December 10, 2019 Can you confirm which version the screenshot was taken in? I was running into issues with grass rendering in the wrong/unexpected direction in 2020, but this appears to be fixed in 2020 SP2. In my test file, everything is now rendering in the expected way. It shouldn't be possible to apply a grass texture to a polyline, so I am assuming you have a nurbs surface(?). Reversing the normal should be a possible work around as well. Quote Link to comment

The latest in French : 2020 SP1.1. The proble appears for the first time I Think in 2018 Yes, sorry, i have 3Dpoly 🙂 . I've tried to reverse the normal without success.... Quote Link to comment
Guest Alex Sagatov Posted December 10, 2019 Share Posted December 10, 2019 Can you send me a copy of the file? You can private message it over to me. You can also remove most of the geometry. As long as the geometry with the grass texture is there, and I have some reference point as to which way its supposed to be rendering. Quote Link to comment

Nico_be Posted December 17, 2019 Author Share Posted December 17, 2019 OH my God!!! Since the update to SP2, there is no longer any way to see the grass up !! I use the terrain modeler every day and the textured areas of grass grow down! Impossible to present this to the client! Could you test on your machines and give me a feedback please?

Nico_be Posted January 8, 2020 Author Share Posted January 8, 2020 @mjm @Altivec After hours of research, I found that if we uncheck "smooth terrain" the texture applies well above! Could you test and send me your result? Quote Link to comment
Markvl Posted January 9, 2020 Share Posted January 9, 2020 Is there anyway to change the normal on a 3D polygon? I've been getting random results when using the grass shader. I'll have some 3D polygons that produce the results you'd expect and I'll have some in the same drawing that don't or rather the grass is shown down rather than up. Quote Link to comment

With 3D polygons, there is no way of adjusting the normals besides flipping them manually. The best option is going to be creating NURBS surfaces in these areas so you can have direct control over the normals direction. Quote Link to comment
skeyshubber Posted February 25, 2020 Share Posted February 25, 2020 I am having the same issue. I'm not working with a site model but simply applying textures to shape objects so I'm not sure how to change the mesh smoothing preference. Quote Link to comment

If you work with a 3D polygon, you only need to reverse the direction of the polygon on the OIP . Quote Link to comment
skeyshubber Posted March 2, 2020 Share Posted March 2, 2020 Actually, to correct my comment above, my grass texture is applied to my landscape area. I can't flip the orientation of this, can I? Any suggestions on how to work around? Quote Link to comment
Nico_be Posted March 2, 2020 Author Share Posted March 2, 2020 Okay, if it's a texture applied to a landscape area then the only solution is to uncheck "Mesh Smoothing" from the 3D Display tab in Site model Settings. Quote Link to comment
skeyshubber Posted March 2, 2020 Share Posted March 2, 2020 I've created a work around with a 3D poly and texture applied to that. Since then, I haven't experienced the issue again. @Nico_be Mesh smoothing is now unchecked and I will test my landscape area. The landscape area I'm working on is a planting bed not relative to the site model in any way other than it just sits on top of it. Does mesh smoothing affect landscape areas aside from the site model? thanks for all the help with this! Quote Link to comment
skeyshubber Posted March 2, 2020 Share Posted March 2, 2020 @Nico_be I have unchecked Mesh Smoothing and my landscape area is still rendering grass upside down. @Altivec My object is a Landscape Area. And I've created a work around with a 3D poly and texture applied to that. Since then, I haven't experienced the issue again. Quote Link to comment

I'll take a look. Quote Link to comment

Nico_be Posted March 2, 2020 Author Share Posted March 2, 2020 @skeyshubber I found a way around the problem: Right-click on the landscape area "Edit path"... Select the polyline and in the OIP click on the last button "Inverse direction" (Inverser le sens in French). Enjoy 😉 Quote Link to comment
skeyshubber Posted March 2, 2020 Share Posted March 2, 2020 @Nico_be ah, merci beaucoup! Quote Link to comment
