Hi, When I perform a calculation using the Compression only support option, I can’t get the results to display without the mesh. Is this a bug? Or can it be configured in a way I’m not finding? If I remove the compression only support option, I can hide the mesh ![imagen](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/c/cbd09aa0eb28dbf0f251ee72267aa6b909904e96.jpeg) Thanks ---

Looks like a regression, maybe related to this: [A new developer/preview PrePoMax version v2.4.5 has been released - #5 by synt](https://prepomax.discourse.group/t/a-new-developer-preview-prepomax-version-v2-4-5-has-been-released/3258/5) ---

Hi FEAnalyst, This also happened in previous versions Furthermore, it only happens when I configure mesh options other than Meshing parameters, that is, if I use compression only support and include a particular mesh configuration (for example, a structured mesh) ![imagen](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/5/53fddb1f75e986791cfb9be4d649937c10cc8017.jpeg) ![imagen](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/0/00b5c5bcb1467c5f7e47fcd270659dbd0fa5af63.jpeg) Thanks ---

It seems to be caused by the use of the experimental pyramid elements. [Cube\_pyramid\_gap.pmx](https://prepomax.discourse.group/uploads/short-url/eyedNOMJuCP3javYWe6nIu2Z9Ue.pmx) (761.8 KB) ---

I think I know why this is happening and I will try to fix it. ---

As a workaround for now, you could use the No edges mode: ![no edges](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/f/f4daa920e5fa15ee804a1a2d5f1f68151abb6865.png) or render in ParaView: ![paraview_surface](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/2/2f6ad3d036c693d40eaa0ebb2e6924fcbe44bbad.png) ---

Hi, I don’t know what the difference is, but I still see the same thing. ![imagen](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/7/791d9d024dfd9d4ea6ae2aef5e298ec666041271.jpeg) ---

That’s because you have the undeformed and deformed shapes overlaid: ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/9/9ca76625f863ab3060424b112ef414c07d6ba524.png) Try with the deformed shape itself (button on the left from the one currently pressed). ---

It’s ok in v2.4.6 with my cube test model shared above. And with Victor’s model too. ![image](https://global.discourse-cdn.com/free1/uploads/prepomax/original/2X/1/1774d8f73bdb8cc6cfe528553a87f281789298e7.png) ---
