| In the FBX exporter set the Units to "Centimeters", this will scale the model up 100 times, as in UE the units are 1 unit = 1cm, while in CS they are 1 unit = 1 meter

|
| You cannot import a skeleton by itself, if you export only the skeleton from max with FBX, UE will import nothing, you need some geometry associated
| | If you want to know why we are doing this, check [http://www.planeshift.it/article/2015/Lets%20make%20PlaneShift%20Unreal this post]. |

|
| OLD (Bake Animations fixes this problem): FBX export seems to have issues if the controllers or bones have a "orientation constraint" on the Motion panel under assign controller. With that it doesn't export, without it does
| |
|
| |
|
| OLD (Bake Animations fixes this problem): UE doesn't import skeletons with multiple root bones, need to have one
| | We are currently using <font size=5>Unreal engine 5.1.1-release </font> (use only this tag when checking out sources) |
|
| |
|
| You cannot import DDS files, unless they are specific format. Better to just import PNGs.
| | == Roadmap == |
|
| |
|
| Only way I found to import a char is to hide all helpers, shapes, then select geometry and bones, and "Export Selected" to FBX with "Bake Animations" selected.

| === Types ===

|
| |
|
| | | [[Unreal Engine resources]] |
| csString -> psString or FString
| |
| | |
| psStringArray with TArray<psString>
| |
| | |
| uint -> uint32
| |
| | |
| csHash<Value,Key> -> TMap<Key,Value> (notice the swap of Key and Value)
| |
| | |
| csArray<> -> TArray

| | |
| === Types conversion ===
| |
| | |
| | |
| FString to char* -> const char *myData = TCHAR_TO_ANSI(*NameString);
| |
| | |
| FString to TCHAR -> *myFString
| |
| | |
| char* to FString -> ANSI_TO_TCHAR(NameString);
| |
| | |
| | |
| | |
| === Functions ===
| |
| | |
| | |
| Replace string.Format("hey %s", string) with string.Printf(TEXT("hey %s"), string)
| |
| | |
| csString.Truncate(5) -> FString.Left(5)
| |
| | |
| csString.DeleteAt(start,count) -> FString.RemoveAt(start,count)
| |
| | |
| csString.Downcase() -> FString.ToLower()
| |
| | |
| output.Insert(0, time_buffer) -> output.InsertAt(0, time_buffer)
| |
| | |
| output.GetAt(output.Length()-1) -> output [ output.Len()-1 ]
| |
| | |
| Cross platform types are defined in Platform.h , like uint32. Those can be included with #include "EngineMinimal.h"
| |
| | |
| CS_ASSERT() -> check()
| |
| | |
| strcasecmp and strcmp, I added those two defines, so the code can stay as it is
| |
| | |
| #define strcasecmp(expr1,expr2) FCString::Strcmp( ANSI_TO_TCHAR(expr1), ANSI_TO_TCHAR(expr2)) == 0
| |
| #define strcmp(expr1,expr2) FCString::Stricmp( ANSI_TO_TCHAR(expr1), ANSI_TO_TCHAR(expr2)) == 0
| |
| | |
| CPrintf(CON_CMDOUTPUT,str.GetDataSafe()); -> UE_LOG(LogTemp, Warning, TEXT("%s"), str);
| |
| | |
| time(NULL) -> FString buf = FDateTime().GetDate().ToString();
| |
| | |
| === FText and Localization ===
| |
| | |
| | |
| FText is Unreal's class for user viewable strings. It is localizable. See https://docs.unrealengine.com/latest/INT/Programming/UnrealArchitecture/StringHandling/FText/index.html
