Why am i getting dents all of a sudden while using subdivision surface modifier? And also i did not use mirror modifier.

I tried to subsurf this model that I mirrored but when I use subsurf it splits the model into two objects.  Before Subsurf:   After Subsurf:   Any help would be appreciated.

I followed a microdisplacements tutorial on Blender Guru and I was able to create a texture fine. Here is a picture.  And then I turned on Adaptive subdivision. Here is a picture of what happened.  I know that this question has been asked before but I am using blender 2.79 so it should be fixed, right? Please let me know you ideas. Thanks

now it is last thing in my first project in blender. I made the model below in images and I thought everything is going well until I rendered it then I saw the quality is bad around the object that I built? Is there any thing that I must do in render to have better result? I will attach blender file to take a look.

hi, why the model looks weird. no double face or normal flip?  I include the blender file

How can I use the subdivision surface modifier to create more high poly meshes without ruining sharp edges? For example this mesh  The sphere should be subdivided but the rim of the cylinder should stay the same because it is a sharp edge. This is the result of the subdevision  How can I get sharp edges to not be affected by the sub surf mod?

i came across a photo where the gradient looks like it s smeared from cream. It is hard to explained by saying so here is the  Let say i create 2 similar shapes with the gradient pattern then adjust the opacity but the edges will still remain. But in the example the edges are appeared to be soft and hard randomly. Thanks in advance !

I work with Blender 2.81a and I have a problem with some artifacts in the shadows of objects with smooth shading. Based on the release note of Blender 2.81 ,(), I expected this problem to be solved. There’s a note with a comparative screenshot saying: “Reduced shadow terminator artifacts for bump mapping with diffuse BSDFs.“   There’s no detail about the issue. There’s a mention about “bump mapping”. I have another scene with bump mapping and the problem is the same as in my test shown below. Here’s a screenshot of my test below.  The only solution right now is to increase of the number of polygons with a “Subdivision Surface” modifier. However that makes a crazy amount of polygons and the modifier cannot fit all situations.  Another element of solution is about the light. I noticed that happens particularly when there’s one directional light in the scene like a sun light. Increasing the “Angle” parameter creates a smoother effect. Too much of this becomes blurry and unrealistic. My screenshot shows a sun with the angle 6.4 degrees.  These artifacts only happen in Cycles. Eevee seems to be correct.  I expected this problem to be solved. However it is still present. Am I missing something?

Is there a way in Blender to push faces like Sketchup does?     The best I can get is doing a regular extrude and a lot of work to clean the "mess" up...    Thank you for your time!

I'm currently modeling my game character in Blender (see below picture).  What is the difference between a subdivision surface modifier and a multiresolution modifier? I know they smooth the surface but are there specific characteristics to using each and what are those?

This is probably a very simple question, but the Mirror modifier keeps mirroring my model though i've applied/deleted it.  I read somewhere that I have to disable symmetry lock, but I'm assuming that only works in Sculpt mode which I'm not using because I'm trying to make a low-poly model. I'm not entirely sure why this is happening because I've done it before and I didn't face any problems.  If i can get some help that would be great!

So I made a 3d model of a sword, and when I try to render it, the program automatically smooths everything out.   Basically, I looked around online, and made sure everything smoothing related discussed there was turned off, and they all were, what should I do?

I am relatively new to Blender so please excuse me if this is rather amateur!   The bottom of my torus has poor surface quality, I have scaled the vertices down for a smaller (variable) tubular radius all the way around the torus and at the bottom the surface quality is awful, with inaccurate shading. Any ideas as to what is wrong and/or how I could fix this?  Thanks, itsanate

Often with imported OBJ meshes I noticed that some seemingly random vertices are surrounded in dark blotches and sometimes adjacent ones are pale. Yet all the readable characteristics are identical to a normal vert angle stats. So why when I was messing around I unchecked Auto Smooth did theses anomalies go away?

So I was doing a fairly simple model of a Glock hand gun. I had already applied a mirror modifier to the model, that I had so far (which was the grip). Then I applied the subdivision surface modifier. At the point where the mirrored part of the model and the "real" part of the model met it collapsed inside of itself. Bellow will be a picture of the model. I would really appreciate it if someone could tell me how to fix this so I can get back to working on my model. Also the picture is the bottom part of the grip, it may looks like two smaller grips, they are supposed to form one. But like I said it collapsed in on itself.  Thanks, Nova

I have a simple cylinder which is mirrored on both the X and Y axis.  When I scale it along the X axis, the two halves of the cylinder overlap, rather than scale as it would before the mirror modifier was applied:    I haven't used Blender in a while and I know this is a simple fix.

How can I enable adaptive subdivision in Blender 2.8? I have a noise texture plugged into the displacement output for a material, with the displacement method set to Displacement Only. There is no "adaptive" option for my subdivision surface modifier, however, when I increase the subdivision levels manually, the mesh is displaced in the rendered view.  I am rendering with cycles with the 2.8 beta version downloaded today.

I have been trying to make a short clip of a bullet hitting a wine glass with wine in it, but I keep running into the same problem with the add-on. Every time I have used it the result has left me with at least a partial box being generated as several of the fractured pieces.  I have tried subdividing and/or adding a sub-surf modifier but the result only changes where the large distorted fragments end up. I have been having trouble with this for quite some time and I would greatly appreciate any help.
