Well, if you drag-n-drop either of the images into the viewport in CE, the terrain creation dialog will come up. Best do this in a new scene, for both image files. If the propoposed scene coordinate system (SCS) and the extent/offset don't exaclty match for BOTH images, the georeferencing info is wrong. What you then can do, e.g. if one of the files does not have a proper georef definition or e.g. does not recognize a projection, therefore falls back to metric scene coordinates, use the one that has proper georeferencing data, CREATE the terrain and then edit the texture file in the terrain object. The reason for this is that when you're still in the terrain creation wizard, loading a new map will reset the extent in the wizard. If the terrain is created, loading a new picture will only edit the picture. But the images MUST MUST MUST depict the same extent, since basically BOTH of the textures are only 'draped' on top of the terrain geometry (scaled to the ends in both dimensions). The georef info is only used to create the terrain geometry, the images are then mapped over this geometry, even if the extents don't match. So be very cautious. Ok?

@Ben: Thanks for helping out here. It's well possible that your heightmap file does not have proper georeferencing data. Are there a .prj or a 'world' file accompanying the tif file? The resolution itself does not matter. It's just the geographic extent that matters: BOTH images have to show the exact same geographic location/'rectangle'. I know.. this all is very confusing since there are so many factors to consider. Maybe post all the files on dropbox and share the link. Somebody here could then have a look at the files. The thing you can also do is write to [email protected]. Ok?

Hi, 'Visual CGA' is discontinued .. that's actually the reason why the toolbar is no more there .. I'm sure something more powerful will come one day!

Hi, When you load an image file in the terrain creation dialog, CityEngine adapts the size of the terrain. I'd say create the terrain first, THEN choose an other file. Also, make sure BOTH files (satellite / elevation) have the absolute exact idential extent and projection. --> So basically, check if visibly, everything lines up in both files. Cheers!

Hi, Well, 4k x 4k subdivisions results in a 16 million poly terrain. total overkill. CityEngine does have a limitation in the terrain functionality and does not have adaptive subdivision for terrains implemented or TINs (a specific precise terrain triangulation). I can only recommend to reduce the terrain subdivision in this case - even if you're losing some of the detail. At least for the time when you're working / editing the scene.

Hi Valerio, You only have 368'000 polygons, that's not a lot. First of all, when working in CityEngine, I NEVER generate all models unless I need it for screenshots. If you're creating code or editing the network, you don't need the generated models. This saves HUGE amounts of resources. The second thing: Try to optimize the terrain's subdivision (check docs!), this usually is a lot of polygons by default. Third, make sure you deactivate shadows and ambient occlusion to make the viewport display your data quicker. Let me know if this helps. Cheers! m.

Hi Valerio, Did you create the terrain image in ArcGIS? If so, does the terrain line up there? Does the image have the exact same projection as the other data? To fix this quick and dirty, select the later, press 'w' and move it into position. Of course, you want to have a proper solution.

Hey .. If the proplem occurs with 400 ish footprints, it could come from one single footprint. Depending on the code, it could be an 'endless recursion' or a geometric/topological issue. Veronica, can you try and track it down by eliminating elements that don't seem to cause this issue? Make a duplicate of the scene file, then: - delete terrain - generate models 'per rule file' (if there are multiple rules involved) - also, analyze, if the issue comes up when you generate the models multiple times, having an eye on the right mem-indicator. - you can also do a 'binary search', generating half the models. if that goes well, the other half. if you run into an issue with one of the halves, go to a quarter of the scene, and so on. I've had it in the past that one 'sliver' shape that was 1 meter long and a fraction of a cm wide caused the exporter to crash. binary search was the method to find that shape. Let me know.

Hey Veronica, If the native side (C++) is out of memory, then I'd say there's something wrong with the model generation. Do the models take unusual long to generate too? Let me know..

Hi .. In what industry is that client working? This may be helpful. There are many different scenarios that could be possible, so I need to know a bit more info .. I'd ask the client for more specifics. Let me know..

Hey, CGA can sample a terrain only once, at the start shape, each consecutive polygon (shape in the model hierarchy) you create with CGA can not sample itself. Therefore, what you ask is not possible to do in CGA alone. My tip is: 1] Create the shapes as you have them in CGA 2] Convert the model to shapes 3] Align those shapes to the terrain using 'alignShapeToTerrain' Ok? m.

Ok .. let me know what comes out .. Note: I find it really sad that macs don't offer the newest generation PC CPUs and GPUs. This is a killer, at least for me. Nice design and a 'painless' OS (except all the damn updates all the time) is cool, but I need more power for 3D and rendering, leaving Apple products sadly as no option.
