Strange behavior on Plotter

[ttsesm]

Hi @marcomusy,

Do you have any idea what could be causing the following behavior in the Plotter. When I load my custom mesh files I get this:

When I load instead any other mesh alternative it seems to work fine:

The code that I am using the following:

vp = Plotter(shape=[5,7], axes=0, interactive=0, sharecam=False)
video = Video(os.path.join(dirname, box+".gif"), backend='ffmpeg')  # backend='opencv/ffmpeg'
video.options = "-b:v 8000k -filter_complex \"[0:v] split [a][b];[a] palettegen=stats_mode=single [p];[b][p] paletteuse=new=1\""

for t in np.arange(0, 1, 0.005):
    for i, mesh_model in enumerate(mesh_models):
         t1 = mesh_model.filename.split('/')[-1].split('.')[0]
         vp.show(mesh_model.lighting(style='ambient'), t1, at=i) # this line gives the first gif
         # vp.show(vd.Cone().lighting(style='ambient'), t1, at=i) # this line gives the second gif
         cam = vp.renderer.GetActiveCamera()
         cam.Azimuth(2)
     video.add_frame()

video.close()
vp.show().close()

The error happens inside the vp.show() inside the for loop and if my custom meshes are more than 30.

Hi @ttsesm although i'm not 100% sure it might be due to the limited number of textures that your system is capable of handling, does it also happen if you do not add textures?

Hi Marco, interesting it seems that you are right. If I do not load the textures it seems to work fine.

However, I do not understand what do you mean that my system is not capable of handling this amount of textures. Do you mean memory wise or something else? Moreover, is there any simple workaround to this?

[marcomusy]

To my understanding (but i'm not expert at all with this..) graphics cards can only manage a finite number of textures in the same rendering. I'm not sure why and unfortunately I have no ready workaround for it...

I see, then I think I will just create two separate gifs instead of one.

Thanks Marco, your help is always appreciated ;-).
