GeNa Terrain extension not covering road surface

[mroshaw]

Hi!

 

I have a Road Spline across my game map. I'm using the GeNa Terrain Extension, "Texture", to apply a sandy track texture, with the intention of having a path for the player to follow.

 

When I go to apply the Terrain extension, I get a weird, very patchy preview of the impact of the operation:

 

 

And of course when I go to apply the texture, it's only effecting those blotchy areas.

 

How can I get the terrain texture to apply to the entire road surface?

 

I'm using Unity 2013.3.17f1 and GeNa 3.4.2.

 

Many thanks!

I've updated to 3.4.4 and that's fixed the issue.

 

The effected area seems to be significantly offset from the actual spline, though:

 

 

See how it's shifted / weighted towards the right hand side of the spline?

 

What can I do to get it in the middle?

 

Thanks!

I've now completely broken it, somehow, and when I click on the Texture extension I get a load of errors in the console:

I was going to say about your prior responses that it is a known issue and it has been resolved in later versions. 

However, the fact that you are getting spline data that's offset and experiencing errors are a major cause for concern. I'll run a few tests today and get back to you.

Okay @mroshaw,

 

After a deep investigation, it appears that you have found a really nice edge case. Internally, I was trying to determine the appropriate resolution of the terrain depending on which mode is selected. You'd notice this if you switch between modes in the TerrainExtension. I found a little while ago that I needed to apply an offset of 1 texel in order to account for Unity's weird scaling issue. However, I just noticed that this is not necessary when using 'alphamapResolution' hense why ONLY the Texture mode was producing incorrect results.

Happy to inform that I fixed this issue and it will be introduced in a new version (hopefully released by today).

Hey @mroshaw, 

A new version of GeNa Pro has been released just now. Please download the latest and let me know here if this issue still persists! 👍

[mroshaw]

That's amazing Manny, thank you! 

 

I seem to be the master of the edge case! Maybe I should get a job in testing?! 

 

I'll download and test the new version over the weekend. Thank you again! 

[mroshaw]

Hey @Manny! Just to let you know, I've just updated GeNa to 3.4.6 and the texture extension looks perfect! 🙂

 

Thanks again!
