Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Increased Vertex Count after Importing FBX

Hi,

I have Imported some Static Meshes in both UE4.14 and Unity 5.5, which were Created in Maya & Max (2014) and Exported from Max (2014).

The UVs were Mapped for each Mesh. The Mesh was also Triangulated before Exporting.

The Vertex count Triples and Doubles for UE4 and Unity resp (Ratio NOT Consistent but Increases the Vertex Count).

Is This an expected Behavior in Game Engine(s).

If SO, then How to reduce the Multiplication of the Vertices during Import. If NOT, then any Guidance would be much appreciated.

I have attached relevant Images for Reference:

Maya:

Maya 2014

UE4: Without UV's Shown

With UV's Shown

Unity 5.5:

The Image's Links are

Thanking, Hitarth

Saw this Question but did not understand @Deathrey's Comment:

Make edges soft in your modelling package. If you are after flat shading style, check this thread.

Thanking, Hitarth

Hi,

I've seen vertex count increase in various game engines upon import, but not exactly triple the amount.

Normally, you see verts increase where you have UV seams/islands, normals that are not shared, smoothing groups, etc, there's also export options that can impact vert count in 3dsmax (ie split per vertex normals).

You might want to investigate further and play with export(3dmax) and import(UE4) options. From the pictures provided, my guess would be due to normals being imported or exported on the dome, in 3dmax it looks smooth where in UE4 you can see individual faces, might be that split vertex normal thing?
