Surface Hatches not aligning with Renderworks Textures

Recommended Posts

Is anyone else regularly having trouble getting Surface Hatches to align with the Renderworks Textures they're assigned to, in spite of them aligning perfectly within the definition? I'm getting all sorts of different results based on the object type (parametric, e.g. walls, generic solids, extrusions, etc.) and the Map Type (Plane, Auto-Align Plane, etc.). Only rarely do the geometries coincide as expected when switching between, say OpenGL and Hidden Line render modes. See the attached example with an extrusion – here the pattern jumps horizontally for me when switching between the render modes. This is really frustrating our efforts to go fully 3D and get both our 3D and 2D views from the same model, as one uses OpenGL or Renderworks, and the other Hidden Line...

 

Cheers,

Markus

Thanks Alan, I've done that, and I often get misaligned surface hatches regardless of whether the mapping is set to auto or not. In the attached file, for example, it's set to Auto-Align Plane, but the Texture and Surface Hatch still don't align when you switch between OpenGL and Hidden Line rendering (let me know if you get a different result with it)...

@Markus Barrera-KolbHi, I think the issues lies with the fact your objects are in an obliqe rotation. I drew in top plan view and when i changed the offset to a number then back to 0 all realigned, but with yours they didnot go back aligned.

Try that, HTH

...I can't imagine that the intent is for surface hatches to only align with their respective textures when in Top/Plan view rather than in a 3D view, or am I misunderstanding? Here's the file with an extrude I just created in Top/Plan view, with no H or V offset, and the hatch still doesn't align with the texture, regardless of the map type. I think this whole feature is either buggy as all get-out or insanely difficult to use correctly. Wish it'd get fixed!

I, too, am frustrated with what I believe should be default behavior: Surface hatches should align from the bottom up (default zero Z height for hatches in architectural objects). The hatches in wall components seem to align only when the wall component is set to follow the horizontal plane (i.e., no top wall peaks). See two exhibits attached. I've looked in vain for a silver bullet parameter setting in the hatch definition, the texture and in the wall object. My assumption was that the mapping would be per the wall definition "Auto-align plane" and/or "Use World Z for origin." Neither helps. If anyone reading this can point me to the right recipe, I'd be thrilled.

This misalignment of surface hatches is a massive pain, and something we encounter regularly.  It takes a lot of trial and error or touching up with annotations to correct.

If you could specify in the object info pallette the origin point for the hatch on each wall or surface, that would make it easy.

Same issue here with a current project. Either allow us to separately apply surface hatches and textures for rendering. Completely different set of controls for each. And then we can adjust them as needed. Or they should perform and align the exact same. Otherwise why have them associate? Very frustrating.

The Surface Hatches feature has always behaved really badly (and I have complained and filed bugs). Here's hoping the engineers make fixing these flaws a priority.

I did get one to work and align last evening finally. But I had to create a texture from scratch using the brick shader and I made it so it worked and was to the exact dimensions for the project. Then I had to make a custom hatch for the bricks to the exact same dimensions and then adjust a few times within the resource browser to make it work. The logic to create all this was not very logical, or straight forward, but it works! Then apply the textures to the walls and adjust the texture offsets and such.

However this all took a long time to dial in. about 4-6 hours. Not counting all the time lost trying the presets and textures and hatches provided. I am hoping I can remember and refine the process more and use this base brick texture with its surface hatch for creating more textures and surface hatches with better alignment. However I am not convinced yet that what I made is "fool proof" but it works for this project. That being said there was not logical connections between the texture and the surface hatch when editing them. I actually have the surface hatch off set from the brick surface texture w/in its resource browser settings. And somehow these two being offset in that environment makes it so the brick and its surface hatch pretty much align in 3D space. Not sure why its working, lol but its working for now. Kinda just eyeballed it until it was doing what its supposed to.

And creating hatches from scrach, thats an interesting one as well. Not user friendly for sure. Anyways, here is what I came up with and its look in model space.
