Hi there

Brushes are fine for trees, but very large when painting grass, see attache - is this correct or can someone assist me with settings?

Does not look correct to me, way too big. But I can't think of an explanation - it looks like you are on the prefab CF terrain, right? Or did you create a new terrain from scratch?

If it's the latter, could you post an image of your terrain settings? Perhaps the detail resolution is way to large... just guessing, though.

I noticed when I start from scratch I often end up with a bigger brush than I would like...  there is a way to fix it but I can never remember how to do it. I also recall Mike saying that it can be problematic to change it later in a project.

Maybe just leave it out this time then

What is your detail resolution set to for the terrain in the inspector window?

[johnmeyer]

 Low resolutions will mean larger Size 1 brush sizes. The terrain settings key resolutions that affect the brush size are:

 

Heighmap resolution - Sculpting terrain brush size

Detail Resolution - Grasses brush size

Control Texture resolution - Paint terrain texture brush size

 

As mentioned if you change any of these settings it may/will delete out your heightmaps, and planting and textures. I use a paid asset called Terrain Quality Manager that allows you to change the control texture and heightmap resolutions without losing them, but detail resolution I believe must be set at the very start.

 

Further more looking into the detail resolution per patch, I was told this is a way to move the details (grass) loads from GPU to CPU. Ie the higher the res, the less draw calls so less CPU load but more GPU load and vice versa. Cant say Ive played with it much, normally set at 8 or 16 on stuff Ive worked with. Not sure its a big deal in the grand scheme of things, but not sure. 

 

Apologies Brendan if this is on the Sun City terrain, as I dont think it the detail resolution wouldve been upped when it was created.  We discussed the control and heightmap resolutions when pgapro went about creating them, but didnt think to look into the detail res.

Thanks John, that makes sense. Yes, it is sun city

Thanks for getting the maps there in the first ppace

Yes John,  You prob have details res set at 128 in inspector. change them to 2048, think it gives a warning regarding splines and textures will be lost, so its best to change these values before you start in earnest.

You won't lose any splines just any grasses that you have planted. Shimonko wrote a utility to change both terrain detail resolution (for planted grasses) and control resolutuion (painted textures) among others a while back so I will dig the link out and post it.

[johnmeyer]

Thats great Mike, will come in very useful for sure.

[Brendan]

they are set art 128. To be clear if i change it i will not loose my splines?

[Brendan]

took the leap and................. i have a working brush. Thanks
