让RenderDoc批量导出纹理

RenderDoc导出纹理时只能一张张导出，非常麻烦，改一下RenderDoc，效果如下

一、qrenderdoc\Windows\TextureViewer.ui中追加2个按钮

<item><widget class="QToolButton" name="saveTex"><property name="toolTip"><string>Save selected Texture</string></property><property name="text"><string/></property><property name="icon"><iconset resource="../Resources/resources.qrc"><normaloff>:/save.png</normaloff>:/save.png</iconset></property><property name="autoRaise"><bool>true</bool></property></widget></item>
<item>// 追加以下代码<widget class="QToolButton" name="saveTexs"><property name="toolTip"><string>Batch Save Textures => d:\\capture\\ </string></property><property name="text"><string/></property><property name="icon"><iconset resource="../Resources/resources.qrc"><normaloff>:/save2.png</normaloff>:/save2.png</iconset></property><property name="autoRaise"><bool>true</bool></property></widget></item><item><widget class="QToolButton" name="saveAllTex"><property name="toolTip"><string>Save all Textures => d:\\capture\\ </string></property><property name="text"><string/></property><property name="icon"><iconset resource="../Resources/resources.qrc"><normaloff>:/save3.png</normaloff>:/save3.png</iconset></property><property name="autoRaise"><bool>true</bool></property></widget></item><item>

二、qrenderdoc/Code/Resources.h中追加2个图标

  RESOURCE_DEF(save, "save.png")                                        \RESOURCE_DEF(save2, "save2.png")                                      \RESOURCE_DEF(save3, "save3.png")                                      \

三、qrenderdoc/Resources/目录中添加几个新图标，save2.png, save2@2x.png, save3.png, save3@2x.png

四、qrenderdoc/Resources/resources.qrc中追加2个图标

        <file>save.png</file><file>save2.png</file><file>save3.png</file>

五、在qrenderdoc/Windows/TextureViewer.cpp中追加代码


static TextureSave tmpSaveCfg;void TextureViewer::SaveStageResourcePreviews(ShaderStage stage,const rdcarray<ShaderResource> &resourceDetails,const rdcarray<Bindpoint> &mapping,rdcarray<BoundResourceArray> &ResList,int &prevIndex, bool copy,bool rw, const QString& savePath)
{for(int idx=0; idx < mapping.count(); idx++){const Bindpoint &key = mapping[idx];const rdcarray<BoundResource> *resArray = NULL;uint32_t dynamicallyUsedResCount = 1;int32_t firstIndex = 0;int residx = ResList.indexOf(key);if(residx >= 0){resArray = &ResList[residx].resources;dynamicallyUsedResCount = ResList[residx].dynamicallyUsedCount;firstIndex = ResList[residx].firstIndex;}int arrayLen = resArray != NULL ? resArray->count() : 1;const bool collapseArray = arrayLen > 8 && (dynamicallyUsedResCount > 20 || m_ShowUnused);for(int i = 0; i < arrayLen; i++){int arrayIdx = firstIndex + i;if(resArray && i >= resArray->count())break;if(resArray && !resArray->at(i).dynamicallyUsed)continue;BoundResource res = {};if(resArray)res = resArray->at(i);Following follow(*this, rw ? FollowType::ReadWrite : FollowType::ReadOnly, stage, idx,arrayIdx);// show if it's referenced by the shader - regardless of empty or notbool show = key.used || copy;// it's bound, but not referenced, and we have "show disabled"show = show || (m_ShowUnused && res.resourceId != ResourceId());// it's empty, and we have "show empty"show = show || (m_ShowEmpty && res.resourceId == ResourceId());// it's the one we're followingshow = show || (follow == m_Following);if(!show){continue;}tmpSaveCfg.resourceId = res.resourceId;tmpSaveCfg.destType = FileType::TGA;tmpSaveCfg.channelExtract = -1;tmpSaveCfg.alphaCol = FloatVector(0, 0, 0, 0);uint64_t currId = *((uint64_t*)&res.resourceId);QString fn = QString(tr("%1\\%2.tga")).arg(savePath).arg(currId);bool ret = false;m_Ctx.Replay().BlockInvoke([this, &ret, fn](IReplayController *r) {ret = r->SaveTexture(tmpSaveCfg, fn.toUtf8().data());});}}
}static uint captureBatch = 0;void TextureViewer::on_saveTexs_clicked()
{int outIndex = 0;int inIndex = 0;bool copy = false, clear = false, compute = false;Following::GetDrawContext(m_Ctx, copy, clear, compute);ShaderStage stages[] = {ShaderStage::Vertex, ShaderStage::Hull, ShaderStage::Domain,ShaderStage::Geometry, ShaderStage::Pixel};int count = 5;if(compute){stages[0] = ShaderStage::Compute;count = 1;}const rdcarray<ShaderResource> empty;QString currDir;for(int i = 0; i < 2048; ++i){++captureBatch;currDir = QString(tr("d:\\capture\\cap_%1")).arg(captureBatch);QDir dir(currDir);if(dir.exists()){continue;}dir.mkpath(currDir);break;}// display resources used for all stagesfor(int i = 0; i < count; i++){ShaderStage stage = stages[i];m_ReadWriteResources[(uint32_t)stage] =Following::GetReadWriteResources(m_Ctx, stage, !m_ShowUnused);m_ReadOnlyResources[(uint32_t)stage] =Following::GetReadOnlyResources(m_Ctx, stage, !m_ShowUnused);const ShaderReflection *details = Following::GetReflection(m_Ctx, stage);const ShaderBindpointMapping &mapping = Following::GetMapping(m_Ctx, stage);SaveStageResourcePreviews(stage, details != NULL ? details->readOnlyResources : empty,mapping.readOnlyResources, m_ReadOnlyResources[(uint32_t)stage],inIndex, copy, false, currDir);}
}void TextureViewer::on_saveAllTex_clicked()
{for(const TextureDescription &tex : m_Ctx.GetTextures()){tmpSaveCfg.resourceId = tex.resourceId;tmpSaveCfg.destType = FileType::TGA;tmpSaveCfg.channelExtract = -1;tmpSaveCfg.alphaCol = FloatVector(0, 0, 0, 0);QString fn;fn.sprintf("d:\\capture\\%d.tga", tex.resourceId);QFileInfo qi(fn);QDir dir(qi.absoluteDir());if (!dir.exists()){dir.makeAbsolute();}bool ret = false;m_Ctx.Replay().BlockInvoke([this, &ret, fn](IReplayController *r) {ret = r->SaveTexture(tmpSaveCfg, fn.toUtf8().data());});}
}

然后头文件中追加

void on_saveTexs_clicked();
void on_saveAllTex_clicked();void SaveStageResourcePreviews(ShaderStage stage, const rdcarray &resourceDetails, const rdcarray &mapping, rdcarray &ResList, int &prevIndex, bool copy, bool rw, const QString& savePath);

然后构建后，点黄色按钮可批量导出纹理到 d:\capture\cap_XXX 目录中
点紫色按钮可导出所有纹理到 d:\capture\目录中
也不会弹出对话框了，实乃挖图利器

导出Mesh可以参考这个
