Crash and bug reports / Re: Mask arrives at Unreal with artefacts

Oh right, makes sense, I'll look into it, thanks for the tip!
By the way if I scale the terrain down to 63x63 then I don't see any artefacts.


EDIT: Setting the bottom most layer's mask to constant 1.0 seems to have fixed the problem! :D

The size of the artefacts (254x254) is exactly the size of a landscape component in Unreal (127x127 quads per section and 2x2 sections per component).

If the artefacts are only visible in Unreal and not in Instant Terra, it may be caused by Unreal.

For one component, if all layers are black, strange things may happen in Unreal, depending on how your landscape material is built. Worst of all, results may vary each time you modify a layer.
This is the case whether the layer data comes from Instant Terra or from other sources.

To avoid this, it may be necessary to have a non-zero (i.e. not black) value in at least one layer for each vertex of the landscape.
In Instant Terra, you can create a mask whose values are one minus the sum of all other masks (use Add and Subtract nodes) and use it for one layer.
This ensures that at least one layer has a non-zero value for each vertex of the landscape.

Fewer artifacts when I replace the flow simulation node with a profile curve.

Crash and bug reports / Re: Unable to start Instant Terra because the version is too old.

Obviously something is getting wrong here. Maybe some files have been corrupted.
I suggest you to uninstall Instant Terra, remove the Instant Terra Unreal Engine plugin, download and install the latest version of both Instant Terra and the Unreal Engine plugin.

I just started getting this message after rebooting, when I attempt to start IT from Unreal:

EDIT: If I keep trying then eventually it starts. However even when it does there is no link to Unreal, I'm forever stuck at "Updating terrain - Waiting for Unreal to respond". The Unreal log shows none of the log prints that usually accompany the process.

- Since I noticed it's always been there, no matter how many times I exported it.

- On a given terrain it's always at the same place. If the topology changes it shows up elsewhere. Seem to appear on flat parts but since this is the sand mask, the problem might lurk hidden on steep cliffs where the sand mask is expected to be black. If I export a fully flat terrain then the issue covers everything, no sand anywhere, only rock.

- I don't remember seeing unexpectedly white or gray squares, only blacks, the missing sand is easy to see.

- A single square is always the same size but their numbers change. I attached the current state: I had to flatten the terrain and now it's really easy to spot the mask bugs.

- I only saw the issue with the sand mask. Even in the sand-mask-bug-squares the gravel layer is proper.

I'll get back to you on the last two things.

Hi,

We were able to open your project but couldn't reproduce the issue. The terrain and the masks we get in Unreal are always correct.

Here are some questions that may help us to understand where the problem comes from:
- Does the problem happen all the time or just sometimes?
- Are the squares always at the same locations or at random locations?
- Are the squares always black?
- Do the squares always have the same size?
- Does it happen only for the Sand mask or also for other masks?
- Does the problem disappear if you decrease the size of the terrain?
- Does the problem disappear if you replace the "Flow simulation" node by a basic mask generator node (for instance a 'Profile curve' node)?
Thanks for your help.

We've just found your email. It was marked as spam. As a result it couldn't be forwarded from the generic address support@wysilab.com to the addresses of the people who usually receive the support requests.
I'm really sorry for that.
We're going to look at your project.

It was sent to support@wysilab.com on 2021-11-17 at 16:12 CET.
At 16:13 I got an automated reply thanking for my message.

Hi,

We didn't receive anything at support@wysilab.com.
Can you check if you sent the data to the right email address?
Thanks.
