I wanted to texture the ground plane in P11 and use it for my scene. Oddly, when I did it, I had to shrink it to 11% or so to get a proper scale. And when I did that, the line still showed up in renders. Any ideas on how to fix those?

Haven't looked into this but there's also under props/d3d_scene/ an environmental backdrop as well as other pieces which might work just as well. Under scene is an alternate construct in the folder environments.

The ground plane is best textured with textures from 8.192 x 8.192 pixels or higher. (16;384 x 16.384) Or work with a tiling using the UV scaling in the texture node. If you see the mesh of the ground plane, you need to adapt your lights.

I personally wouldn't use the default ground plane. I would turn it off & use a high poly square from the primitives folder instead. Default ground plane only has 400 polys where as a high-res square has 4096 polys. I think you'll get crisper results.

If you are using Superfly, you need the enclosed feature of the construct (default ground) for Superfly to properly raytrace a scene. BUT as 3dfineries suggested you can ADD the high res. ground plane just for the ground textures (and raise it slightly above the ground of the construct), or import grounds and other props for that purpose.

Or? As Boni said; Import the high res plane and work with that. And lower the construct to just below floor level. Remember however ! ! ! That a Ctrl+D will drop your figures and props to the Construct floor level, and NOT to the plane you imported to "play" ground.

Tony, that's a very good point! There are a lot of new things to consider with Superfly, but the final render is worth the effort.

"I personally wouldn't use the default ground plane. I would turn it off & use a high poly square from the primitives folder instead. Default ground plane only has 400 polys where as a high-res square has 4096 polys. I think you'll get crisper results."

I'd just like to correct this common misconception if I may. A flat plane consisting of one large polygon will render just as crisply and smoothly as a million polygon plane. Mesh resolution doesn't have anything to do with this. Minimum shading rate and texture resolution are the defining factors for something like this. Texture resolution for obvious reasons, minimum shading rate for less obvious but very important things like shader/image map detail and rendertime micropolygonal subdivision. The min shade rate is basically the detail setting for render. Consider displacement and the profound effect of detail that can be achieved on a single polygon in relation to map resolution and rendertime subdivision for example. The mesh resolution is more important for morphing and smooth bending and non planar real time detail, something that isn't a concern when dealing with a flat plane. Just figured I'd point this out...

Totally forgot about that, EldritchCellar! So right! Try setting your raytrace light's shadow to Blur .4 Samplese 40-60 and Bias to .2 and see if that helps.

I was able to texture the ground plane but had to use advanced panels in the Material Room in order to accomplish this with UV scalers. Made a lovely beach for my figure.
