I created a rock texture and was wondering if 'rock' properties can be applied to it. Ideally, so if a ball lands on it, the ball will react like it hit a rock.

Currently, no.  Only CF splines can have physics properties applied to them.  The general terrain is, however, rough.  You'd have to create the rock as a 3d object in Blender or Sketchup (or other 3d program) and then you could apply a physics property to it.

Art,

Could one or more of the existing rock prefabs from CF be used and resized, reshaped and then sunk in to the ground to try and get UV the effect he is after?

You could draw a concrete mesh around it, then cut the mesh using the scissor/clipping hole spline icon.  The mesh will become invisible but the area inside the spline will still retain the concrete property and balls will react accordingly.   

 

Not the most elegant solution but it's one option.  It's useful if you have flattish rocky outcropping areas that you want to retain the look of their texture painting.

 

Using the rock prefabs is certainly the most common approach.

Thanks for the responses. I've played around with the rock prefabs, but I like the flexibility that painting on textures and manipulating the terrains allows.

Bortimus, I will try your suggestion. Have you done this yourself?

I experimented with it for a terrain painted slanted rock wall and yes it does work.  I decided against it because the rock wall was too vertical and looked better with a 3D object.  

The areas that you are showing would work well I think since they are fairly flat to the ground.

 

Be aware that if a ball comes to rest on a clipped spline, the ball and player will hover a bit because the meshes are built a little above the terrain.  Some players may notice this but if it's concrete the ball will rarely come to rest on the rock.

It's worth a try.  If you want to keep the terrain texturing then it may be the way to go.  

 

Edit:  Since the PP meshes can be triangle intensive,  I wouldn't recommend doing this to every rocky area if you plan to have a lot of them around your course.  Only to the ones that could come into play.

Sure could!

Just FYI, when you alter the dimensions of a 3D object unevenly you will start to get the stretched looking textures as shown on the rocks above.     

If you can't scale them properly to fit the area, it might be better to use several objects instead of trying to make one do the job.

Hi bortimus,

 

I used 2 rocks but the point is taken. I was pretty happy with the results I was looking for. I actually wanted it to be even flatter. Perhaps if I had used a bunch of smaller rocks and stretched more of those flatter. I think I started that way but ended up doing this instead for the effect I was trying to create. I've found that satisfaction with rock stretching and enlarging techniques can be a bit subjective. To me it looks very much like rock features I have encountered in my environs even if not perfectly.

 

Cheers,

I was thinking this same thing myself and I just thought to clone the concrete mesh and to name it as rock. Then I just drop a downloaded seamles rock texture to the layer (resize it) to replace the concrete image or just use the rock textures that were already there in the MJ's tutorial project.

 

Then I just use it the same way as those other spline meshes. And nobody is hoovering above the groud. Not tested this yet, so I can be too optimistic about it. If the terrain's shape is very sharp edged, this may not work too well.

 

I didn't know that the cutted hole in the mesh keeps the settings of the material around it. That's not a good news because those cutted areas are mostly rough IRL.

That's the idea.

I guess only problem using the 3D objects is if the ball rolls in to rock, the collision detection doesn't work, so the player would end up stood in the rock for his next shot.

It will use the physics properties of the actual spline assigned to the cutout so you can make it any texture you want.

Good to know:).
