I have over the past few day’s, come across a problem that i was wondering if someone could help with!.
I have been using blender for some time now so am used to it’s layout e.t.c, however, i seem to over the past few days, come across a problem that either i can’t figure out or that has for some reason, only now started happening!..
I was trying to create a bridge for a scene/ image!.
Using the defult cube, i go to edit mode!.
Subdivide the Cube twice!. ( Front view ) and delete the left hand verts!.
Then add a mirror modifier-mirror on the X-axis to create the cube!.
I then go to side view ( num pad 3 ) and scale along the y-axis!.
So far, so good!.
I then go to see through mode in side view so that i can grab the center verts and grab them up on the z so as to create the center of the bridge ( Where the water will go under ).
Either side, i create two loop cuts and again the same on the other side of the center line!, once again, pulling the bottom of them up to create a better curve shape for under the bridge!.
You need to supply more info.
What version of blender are you using ?
What operating system are you using ?
What graphics card are you using ?
And by the way you have posted this in the wrong forum. This is for ‘News & Discussion’ about blender. Scroll down the list of forums and you’ll see the support forums so you know where to post further questions in the future.
Sorry for posting in the wrong place!.
Couldn’t find it at the time but know now, thanks!..
I’m using blender 2.55
operating System…Windows XP
Graphics card…ATI RADEON X600 pro
AS i say, it’s all been working fine for some time not!.
Have been using blender since 2.49 and other then problems most have had at times, nothing else!.
Utill the past few days!.
It seems to not matter if i add a mirror modifier or not, selecting verts seems to be somewhat random and not the one i wish to pick!..If that makes sense?.
Thank you for helping and for pointing me in the correct direction for the future!.
I think it sounds like a common problem caused by some graphics cards. De-sellect the “sellect front facing polygons” button at the bottom of the 3d view. Its the icon to the right of “vert,edge,face” sellect icons.
It looks like a circle in the lower left surrounded by dots.
This is enabled by default, but it is virtually useless for the majority of users, as far as I can tell, and can cause serious problems when it randomly sellects a vert off screen.
I think, to avoid confusion, this should be “off” as default.
Hope this helps.
I gave your advice a go and seems to work fine like that!.
I do sometimes like to use the front face select when modeling so as not to get too messed up when there are many verts, edges e.t.c!.
i find they can sometimes get in the way when there are lots!.
It has all been working fine for a long time but now for some reason, when i select a vert, blender picks some random one and not the one i want!.
Guess for now, i’ll just have to use it this way, as you suggested!.
Thank you for your help, at least i can still do some modeling e.t.c!.
It usually works ok in face sellect mode. Just Vert and Edge mode cause problems.
Even then ive learnt not to trust it, especialy when I cant see the whole mesh.
It would be interesting to know how many people have problems with this.
If it is specific to some graphics cards, or if it could be called a bug.
I myself find it difficult it times to work with the mesh as see through in face select mode!..
However, as it seems it’s the only way i can build anything right now, then it will do for now!.
Everthing else seems to work fine!.
I render smooth water, smoke e.t.c!.
I do not understand though why it has been working all ok for so long and now, after time won’t let me select them as i should be able to?.
I also agree, it would be interesting to see if others have had the same problem as it maybe something that doesn’t show for a time or maybe something to do with graphic’s cards?.
The thing is, if i am able to render water and smoke very well, build models e.t.c then i wouldn’t have though something like selecting a simple vert would have been so much of a problem?.
Not being a programmer i wouldn’t know though!, lol!..
Something else, i feel maybe due to my error is that when i render smoke, i get the Shadow of the domain on the ground plane?..The smoke looks great e.t.c and the domain isn’t rendered, just it’s shadow…Is there something i may have missed?..
You propably have hardware antialiasing enabled in your nvidia control panel/catalyst control center.
For some reason this causes some vertices to be randomly occluded and you’ll be selecing random vertices every now and then.
Turning off antialiasing should solve this problem.
Jorzi, thanks for the tip. I tried what you suggested, and it does seem to prevent the random picking problem.
Unfortnatly the res of the occlusion dosent seem accurate enough for my use with my system.
Selecting internal edges on a two inch thick walled tube and at the expence of a poor display.
I hope eventually to get a better graphics card which should improve the situation.
I am concerned though that with it enabled by default, a new user might be put off Blender
on there first try if they were not aware, as I wasent, how to solve the problem.
Yes, it could actually be considered a bug…
I managed to get around it in 2.49 by increasing the vertex size in the interface settings, haven’t yet found out how to do this in 2.5
It was actually really cool working with AA enabled when it worked, especially the glsl shaded mode looked awesome
The CPU rendered images are not affected by hardware antialiasing, only the viewport renderer, so your final projects will not be affected. (You can of course temporarily turn it on for taking screenshots etc)
Well, gave it a go and what do you know, it worked!!!..BINGO!!!.
I also try’d after, shutting down blender and turning it back on and still it works!.
i wonder though for how long?..
Glad that it won’t effect the final render!.
Do you think maybe we should report this as a bug?.
If so, how do we go about doing it?.
Thank you guy’s for the great advice and taking your time to get back to me!.
