I just installed SU 2026 and I was interested into the new tools of mesh creation and texture generation based on the point cloud.
Does it work for any of you?
I can’t replicate what is showed in the webinar.
- When trying to generate a texture, after some calculation time I get nothing, no texture is applied to my simple rectangle in front of the point cloud, nor a texture is generated in the material window.
- When trying to create a mesh I have 2 options: if I am in an ortho view I get nothing (after a few seconds of calculations) as a result; if I am in a perspective view, after clicking “create mesh” I am asked (with the pencil icon as cursor) to draw something… I am able only to draw a rectangle - at the opposite corners - which is oriented as the screen, not in perspective, and after a few seconds I get a meaningless bunch of tessellated geometry which is flying in the area. Also the geometry created is a group named: “Terrain Mesh From Cloud Selection” but I pushed the “Surface Mesh” button, not the “Terrain” one.
Any feedback?
Help from Trimble by any chance?
Hi,
Could you provide screenshots of the cloud you re trying to texture with and the surface mesh you re trying to build with the resulting mesh. Also screenshots of your parameters. (If you can share your full data, we can reproduce it on our side as well)
Also, did you have the latest version ? Has your cloud been moved from its original position ?
Best
YS
Thank you for your interest.
I recorded a short video of the problem.
Should I try a more dense point cloud?
Eventually when the rectangle was very close to the point cloud at least a texture was generated, but fully black like no RGB from point was recorded.
I don’t know what to say about the geometry: I didn’t show that the behavior is different when I am in a ortho view: should I record another video?
Could it be that the PC is not on the C drive?
Let me test it.
Nope, it doesn’t solve it.
Instead I put some time checking the “Terrain Mesh From Cloud” tool and it does not work as expected. I don’t use it a lot and I skipped SU 2025 for this reason, being ok with SU 2024.
I recorded a video and I am going to post it on YT as the other
Keep in mind that I reset the transformation (but it was a new file where I linked the RWI file for the first time, so why there was one anywy?)
This reminds me of the permanent issue (every time) of creating the first clipping box from point cloud which it never mathces the point cloud itself: I would imagine that it should fit the point cloud (like other similar point cloud software when you create a visibility bounding box) but in SU is always off, sometimes a little, some other more up to not show anything: then wticking the box I am able to get closer to the point cloud and set it up as I need.
Beware: the video is long… 
Hello, I am Yannick from the SU team and first I would like to apologies for all the trouble.
I went through your video and saw a lot of things^^.
There are a couple of issues in the way you are using the tools that make me think that the workflows are obviously not clear enough and that we will need to go through the UI/UX things to make those easier to understand. I could explain in details later but for now I would like to focus on the real issues that you show.
Obviously the tools (texture/Surface Mesh) don’t find “points” to work with. It is highlighted when you try the “ground mesh” that is created totally off the visible pointcloud : it mleans that SE find the point where they are obviously not and this is why texture and Surface can’t proceed properly.
The first thing I would like you to check is the following :
Could you please, in the project from the video) go to your “components tray” and look for one named “TSE_Manipulator” and especially check if you have more than one of those components
If this is the case (that you have more than one of those) It could definitely explain the issues you have and the solution could be to delete the extra TSE_Manipulator component, at first.
That TSE_Manipulator embed the potential transformations of the PC and is used by SE tools to “know” where the PC actually is. In older SE versions they were somes cases where that manipulator could be doubled (that was a bug) and then make SE confused about the PC real position, that could explain your issues. The counter part is that deleting one of those manipulators could affect the current position of the PC (by somehow reseting it properly). If your project has no particular model yet this should not be an issue.
Some more comments.
If this is not a TSE_Manipulator issue I suggest to start from scratch again. I mean :
- Start SU then Uninstall SE from the extension Manager
- Get the latest version of SE from the extension Warehouse and install it (don’t restart SU in between) : SE version 2025.1013
- Once installed, restart SU
- At this point, the best would be to re-import the PC if possible (not using the current existing RWP but recreating a brand new one). If not possible just try re-opening the RWP in a fresh SKP
Thank you Yannick.
I checked what you asked and the result is that… the issue was my template file, that I have since… forever. - I guess it had a transformation inside that messed up with the location of the PC.
In any case I recreated the RWP file from the original E57 but I don’t think it was that.
There weren’t 2 TSE in the components manager, but after “Reapplying transformation” in the PC manager of SE to the point cloud (something I eventually tried but felt it was wrong to do), things got back to normal. [To me reapplying a transformation means to do something to the default location and move the PC somewhere. Instead looked like the PC was now moved to the default position, substantially the other way around]
Anyway I reinstalled SU, because I was not able to uninstall SE from the extension manager (it failed). [I have to report that I installed (as administrator) SU asking not to install SE (and I downloaded it separately as .rbz) but after installation I discovered (despite asking not to) that SE was already installed. I am sure it was installed freshly because the SE plugin in the old installation was a previous version. In the new installation the plugin is version 2025.1013.]
And now with a fresh install, updated SE plugin and clean template, everything seems to work similar to “What’s new in SU2026 video” 
Still I believe SU will have to create extensive tutorials on how to use these new features.
Now I am going to see how large is the texture map created out of the PC (4K!)
