Hi JD.

Below is the link to the image of my fist Cinema4D and maxwell render at SL13 & 4% complete. I'm having trouble with the grass which does not seem to resemble maxwell grass. I used the Maxwell generic grass material and a grass tag with the Maxwell generic grass parameters for houses. I tried changing some of the parameters slightly but still got the same result. I have tried grass at 100% max 1000000 and 20000. Any suggestions would be appreciated or recommended improvements to the render.

Thank you
Ran

I don't see any grass being rendered in that picture; am I correct to assume it is supposed to be on the green plane in the center of the scene? Regardless, again here, I would recommend trying it in a simple scene (just a single plane) first, to get the feel for it. There might be grass growing on your plane, but without knowing the export scale, and the normal direction of the plane, and the grass settings, it is really not possible to say. So I'd try getting it to work in a test, and then compare that with how your real scene is set up.

As suggested I have been trying for some time in a simple scene with the plane from my model. I have tried many different settings at different scales with no success. The grass appears in my model but does not render with Maxwell. Please can you examine to see what the issue maybe.

It will work fine if you set the grass Cut Off value to something greater than 0%:

Apparently the generation of vectors for viewport display does not factor for this parameter, so I can see why you might get confused.

Thankyou.

Hi JD.
I'm having issues again with maxwell grass in cinema 4d. The grass is upside down on. It is on the underside of the mesh. Do you know how to rectify this problem?

I reversed surface normal & all good.

Yes, that is what determines the direction for grass growth.
