Hi, I’m trying to elaborate some custom tools in Grasshopper, and use them with grasshopper player and/or compiling them into plug-in via Grasshopper ScriptCompiler. Evrything works well into grasshopper document, but when I use the Player (including context bake component) or the rhp plug-in, evrything is right on the first run, but the second time I play the solution, it seems to calculate data from previous run, and it also keep render the solution in viewport, even if I didn’t picked any geometry for the new run. I hope I explained the problem clearly. It also happen with the wall solution example downloaded from: [image] Grasshopper Player Turn your Grasshopper definitions into Rhino commands. Thanks in advance for help

Hi - [image] interkinactive: Is there a way to get someone from McNeel to have a look into it? As you might have seen in related threads, we have looked into this but haven’t been able to reproduce the issue. I’ve been trying again now, using different versions of Rhino on both Windows and Mac, using several of the definitions that are referred to in those threads. I can’t make this happen. If you have detailed steps and a definition, I’m happy to try more… -wim

I created a simple file. To reproduce follow these steps: start rhino draw some geo start grasshopper player and follow the steps do it twice with different numbers or different geo now start grasshopper => the ghosting starts Me with clean Rhino and Grasshopper Player: only the actual choosen objects are previewed [preview_stuck] open grasshopper - an all the last states are previewed (thats what I mean by ghosting): [preview_stuck2] Grasshopper Player used again: third set of objects to be seen: [preview_stuck3] To lock the solver didn’t help. Closing grasshopper doesn’t help. Only closing and reopening Rhino helps. I hope with this instructions you’ll be able to reproduce the problem? I’ve got version 7.12 Rhino (Rhino 7 SR12 2021-11-9 ) ghosted_preview.gh (6.5 KB)

Hi Jess - [image] interkinactive: I hope with this instructions you’ll be able to reproduce the problem? I’m afraid not, no. [image] -wim

even with different preview options it’s like this with my RH [image] First I thought it’s because I usually don’t use a context bake and just jump out of the process. Or because of the use of certain plugins… Or because it doesn’t like blocks… But neither exclusion helped. But i’ll keep trying. As soon as I might find something, I’ll let you know :slight_smile:

@wim Open Rhino (here 7.13) Open Grasshopper and close Grasshopper Run GhPlayer (example by Jess) definition and other when values are entered, there is not automatic redraw refresh, except when I click in the window. [Ghost] [image] interkinactive: How do you bypass it? @interkinactive Preview was set to off, value input does not generate visual feedback, sadly ghosted_preview.gh (6.4 KB)

Hello Wim, I set a relevant example using only python script in this thread : [image] GrasshopperPlayer still running in background Grasshopper Here is another version of this grasshopper using python script instead of an external plugin text_only_once-ghp_cache_issue.ghx (78.7 KB)

I made a GrasshopperPlayerOnce Rhino command if you need. Have a look here: [image] Loading a gh file, executing it and harvesting its data Grasshopper Developer I tried to translate the script Runner in Python language but it doesn’t work. Can someone help me ? I’m close… Runner.gh (5.5 KB) By the way, for a V2 I succeeded to adapt the c# script in a ghpython, it would be great to make a python script directly. If the issue is not solved until then :smiley:

Hello, the problem of ghosted preview is related to Remote Control Panel If you close it from Rhino or Unselect it from Grasshopper > View the ghosted preview disappears

[image] eddi: there is not automatic redraw refresh, Confirm it here, thanks @anon39580149 But there is not automatic redraw refresh,, example when i enter new distances then for display refresh I need to move the viewport briefly.
